Step 1: Gather Materials & Tools
Each of the poi specific items - Kevlar wick, Technora, handles, and splicing fid - include links where you can order them at dark-monk.com. (Disclaimer: I have no affiliation with Dark Monk, I just like their selection and prices for prop supplies.)
MATERIALS (for set of two poi)
- (36') 1/4" Kevlar rope wick
- (2) 60mm wooden balls - I searched "wooden craft ball" on eBay
- (10-12') 3/16" Technora - 10 ft for average-length poi, 11-12 ft for longer poi; you can subtract 2.5 ft if you already have Technora thread
- (2) Handles - I recommend Ultraknobs if you want LED handles, PomGrips if not
- (2) Small screw eyes, 3/8" (10mm) heads and roughly 7/8" (23mm) long
- (17" x 4") 1/8” thick packing foam sheet
- (12) Toothpicks
- Toilet paper roll
- 5-minute epoxy - the kind with two chambers and a plunger
- Disposable stirring stick (a chopstick or popsicle stick works great)
- (Optional) Velcro tape (at least 3/4" or 2cm wide) - if you don't want your Ultraknob lights to fly out
- (Optional) Washers - if you like a bit of extra weight in your handles
- Cordless drill
- 10mm spade bit
- Medium splicing fid (for 3/16" Technora)
- Large sewing needle
- Electrical tape (or duct tape)
- Tape measure or ruler
- Marking pen
- Printer (or place where you can print one simple black and white image)
Step 2: Prep Tethers
Grab your 3/16" Technora, splicing fid, screw eyes, electrical tape, and scissors.
2.1: Collect Technora thread
First we will acquire some Technora thread, which we'll use later to secure our spliced tethers. Measure about 2.5' (75cm) from the end of the Technora and wrap a piece of electrical tape twice around that spot. Cut the Technora directly through the middle of the taped bit.
Take your new 2.5' piece, untape the ends, and carefully peel apart a strand of the rope until you have four ~1.5mm thick pieces of Technora thread (for estimating thickness, go for around three times wider than normal thread, but thin enough to fit through the head of your large needle; see pics for example). Set these four pieces of thread aside for later.
Find the middle of your long length of Technora, wrap it with electrical tape, and cut down the middle of the tape again. You should end up with two pieces of Technora of equal length (between three and four feet each, depending on how much you started with), with all four ends taped up to prevent them from unraveling.
Slide a screw eye on to one of the lengths of Technora down to the middle, fold the length in half, lay it on the ground, and then adjust one side so it's around 2" (5cm) longer than the other side. (The long side is the one getting spliced, and will compress a bit as the short side slides into it.)
2.3: Splice tethers
Insert just the tip of the short side into the bottom hole of your splicing fid (near the rounded end). Now pick a spot just above the screw eye on the long side of the tether, cleanly part the braids with the needle end of the fid, and slide the fid directly up the middle of the long side.
Take care that the fid stays inside the Technora down its entire length and doesn't catch an edge or otherwise pull any strands out of place. Once the fid is fully inside the spliced end, you can start pulling and moving the fid along until it emerges from the top (you may need to loosen up the tape on this end for the needle to fit through).
Remove the fid, set it aside, and continue pulling and smoothing out the spliced tethers until the screw eye is in a tight loop at the end. Ideally the ends of the inner and outer Technora braids should now be roughly in line with each other, but it's ok if the core is slightly longer than the sheath, or vice versa. Just make sure that the spliced length of the tether is at least as long as what you want the final length of your poi to be. We'll trim off any extra later.
2.4 Sew spliced end
Grab one of your 2.5' pieces of Technora thread and pull it halfway through your large needle. Pinch the two ends together, tie a triple knot near the end (see pic), and trim off the excess. Now push the needle through the tether between the strands on each side, pull it tight, pick a spot one or two strands (1-2mm) away from where the needle exits, and push it through again.
The point here is to keep the splice from slipping or loosening up at the critical point near the screw eye. Continue sewing in a circular direction around this ~1 inch long section of the tether near the eyelet until only two or three inches of thread remain. At this point, cut the thread near the needle, take the two ends, and tie another triple knot, pulling tight against the tether. Trim off the excess thread and you're ready to move on to the next step.
- A note about Technora -
A clean splice and tight braid is crucial to the final integrity of your poi. Technora actually has a higher fire resistance (932°F) than kevlar (930°F), which is why we can attach it directly to the wick, but this fire resistance drops precipitously if the braid is loose to start with. You can further prolong the life of your tethers by taking care not to submerge them when you fuel up. If you really want to go the extra mile, splash some water on your tethers near the wicks before you dip.
Step 3: Attach Core
Collect your power drill, 10mm (3/8") spade bit, 60mm wooden balls, 5-minute epoxy, stirring stick, some scrap cardboard, and your tethers from Step 2.
3.1: Drill hole in cores
Attach the spade bit to your power drill and find a flat work surface (a workbench is best, but you can also lay cardboard out on your floor). We're going to clamp or tightly hold onto the ball as we drill a hole into our cores, partially fill it with epoxy, and then screw in our tether.
You want the hole to be just deep enough for the top of the screw eye to be just below the surface of the core once it's been screwed in all the way. For my ~2.3cm long screw eyes, I drilled the wide part of the spade bit just shy of 2cm into the ball. Thus, at the bottom of the cylindrical hole, there was a smaller hole left by the pointed end of the spade bit which the tether could screw into nicely.
3.2: Fill with epoxy and screw in tether
Once you've drilled the tether chamber in each wooden ball, grab a small piece of cardboard, your stirring stick, the epoxy, and your tethers. I'd also recommend a paper towel or preferably a wet wipe as the epoxy can get messy.
Snip the ends off the epoxy, detach the plastic cap piece from the center of the plunger. Squirt a small amount (~20% max) onto the cardboard, aiming for an equal amount from each side, and get ready to work relatively quickly before the epoxy can harden.
Stir the resin and hardening agent together until they're completely mixed, and then carefully scoop the epoxy into the hole in your first wooden ball until it's about two-thirds full. Now push the tether firmly down into the hole (some epoxy will probably ooze out, just let it happen) and screw in a clockwise, righty-tighty fashion until you feel the screw eye screw all the way into that smaller hole in the bottom of the chamber and the tether stops turning easily. Wipe any excess epoxy off the face of the ball around the tether, lay the ball and tether on a piece of cardboard to dry, and repeat with the second ball, mixing more epoxy if needed.
Step 4: Get Knotty
4.1: Print knot template
By far the most complex part of this build is figuring out the exact type of globe knot you want, as there are near-infinite permutations depending on the size of your core, number of pass-throughs to fill out the knot, and thickness of your rope.
Luckily, I did that part for you (with the help of knot guru John Allwine and his grid maker application). Open the "Printable 30 facet..." PDF included in the images section of this step and print it in portrait mode. The PDF format should preclude your printer from adding margins or scaling the image, but if it prints out funky, you might have to adjust your Page Setup options.
Cut the knot pattern out of the sheet - it should be roughly 4" tall and 8.5" long.
Note: If for some reason you're after a globe knot with a different number of facets (e.g. you want to make a bigger head, or use a different thickness of rope wick), or if math just gets your blood flowing, see the end of this section for my calculations.
4.2: Craft mandrel
(noun) a round object against which material can be forged or shaped.
Mmhmm, that's what a mandrel is. Riveting eh? We'll now make one out of a toilet paper roll and packing foam.
Grab your cardboard tube, sheet of packing foam, and some tape. The tube I had is 4" tall, which I hope is the standard height for toilet paper where you come from because that's what the rest of the measurements are based on. Anyway, take your tube and tape the edge of the foam to it, then wrap it tightly around and around and tape down the end.
Take your printed out knot template and glue it around the mandrel. It should wrap around the mandrel just about perfectly (a little overlap or coming up a bit short is ok).
Now take your 12 toothpicks and cut one end (~1/2” or 1cm) off each of them so you don't stab yourself when you're tying your knot. Take your large sewing needle or another similarly sized poking object and make holes on the inside of each bend of the knot image (i.e. on the other side of the rope from each of the A1, B1, etc. symbols). You should push all the way through the cardboard into the center of the tube. Stick a trimmed toothpick into each hole.
4.3 Knot up
Take your length of wick and find the centerpoint - this is what you'll place on the mandrel to start the knot. You can start anywhere you want on the mandrel as you'll eventually come back to the same place, but I usually start at one of the top bends (A1, for example). Just follow the image of the knot, taking care to slip your rope under or over (depending on how it looks in the image) at each point where it crosses itself.
Once you come back to your starting point, you've completed your first pass and are pretty much home free. Take out the toothpicks, slide the knot off the mandrel, and insert one of your tethered cores into it. You'll now complete two more passes to fill in the knot over the core. This means simply following the first pass all the way through, copyingnthe overs and unders exactly until you run out of wick one one end, then continuing with the other end until you've completed three full passes. In other words, each square section on the knot face should have three bits of rope visible.
When you've done three passes, you should have a little rope sticking out and a lot of slack in the knot to take care of. Start a few overlaps away from one end, pull that section tight (not insanely tight, just enough so it will definitely lie flush), move onto the adjacent section, rinse and repeat - allllll the way through all three passes till you reach the other end. You should have a beautifully round knot with no slack left. Mazeltov! Trim the excess rope with some wire cutters/sharp scissors, leaving the end tucked beneath the nearest "under" section (this one section should effectively have four passes, but they shouldn't be visible).
Repeat for poi #2.

Step 5: Add Handles
5.1 Choose length
To find the right tether length, the easiest way is to grab a pair of poi that you really like the length of and lay one on the ground with the tether full stretched out. Pull the handle up or down the tether until the handle tops and head bottoms are in line. (Alternatively, if you don't have a decently-sized poi set to compare to, you can measure from the bottom of your hand to the top part of the shoulder as a good general length for poi.) For the second poi, measure it against the first.
Once you've found your length, thread your needle with Technora thread and secure the spliced tether in the same way you did near the screw eye at the other end. Once you've gone around a few times, pull the tether through the bottom of the handle a bit more (making sure not to pull it all the way out if you don't have much extra coming out the top) and wrap the thread tightly around the tether as you move upwards, creating a ~1/4" wrapped section that will be inside the handle hole. Push the needle through the tether again at the top of this section, sew a few more times around, then cut the thread near the needle, take the ends and triple knot tightly against the tether, and trim the excess.
The purpose of this sewed section is so that, when we trim the extra tether in the next step, the Technora will fray, but only down to where we sewed.
5.2 Prep handles
Pull the tether through the handle in the other direction, out the top, until the handle is well below the sewed section. Cut your tether about 1/3" above the sewed section, slide any washers you want on for extra handle weight (I added two, but next time I probably won't add any), and then purposely fray the end so it's completely spread out in a big poofy circle. Now pull the tether back through the handle till bottom of the sewed section is where you started it, against the bottom of the handle.
If you're using Ultraknobs, I highly recommend cutting two 2/3" Velcro circles (the pokey side of the Velcro), as the light inserts have a tendency to eject when you drop them and the Velcro will prevent that.
5.3 Make epoxy plug
Once both your poi are sewed and trimmed and frayed, collect your epoxy, cardboard, stirring sticks, and paper towels/wet wipes. A pair of tweezers will also be handy if you're adding Velcro.
Squirt out a good portion (around 1/3) of your epoxy. Stir it up well and then scoop it into the bottom cavity of the handle, mixing it underneath and around the frayed tether till the fray is saturated. Continue scooping in epoxy until the small circular cavity in the bottom of the handle is almost full. Leave this handle laying upright (I hung the poi from a door handle) and repeat with the other handle. Now is the time to tweezer or otherwise gently lay the Velcro circle on top of the partially dried epoxy in the first handle - you want the pokey hairs protruding just past the top of the small cavity into the wider handle area, so add more epoxy if necessary. Add the Velcro to the 2nd handle as well. If the epoxy is too dry to press the Velcro into at this point, you can always super glue it.
Let both handles dry upright for at least 30 minutes to make sure the epoxy is fully hardened. While you wait, you can cut out two 2/3" circles from the furry side of the Velcro and glue those to the bottom of your silicone Ultraknob light inserts. I find that longer-drying Gorilla Glue keeps the Velcro attached to the silicone more effectively than Loctite or other instant-dry glues, but it will probably still need to be reglued every so often.
