This is a way to power some LED necklaces with a less-bulky battery pack. This needle felted battery holder attaches at the back of the necklace, which also makes it easy to have a light-up jewelry piece that only turns on when it's clasped.
If you are as excited about the possibilities of mixing needle felting, the most addictive fiber art on the planet, and soft circuitry, here's a nice little exploration.
Step 1: Materials & Tools
- A hunk of wool roving in whatever colors you like - less than 1/4 oz
- 1 or 2 felting needles
- 1 piece of foam
(Bekathwia has a great starter kit for sewing LED circuits. She's the one who taught me!)
- a 3v coin cell battery
- Conductive thread - about 24"
- a Sewing Needle
- 2 Figure-Eight Eye Rings
Step 2: Wait!! Read Me!!
Felting needles are sharper than the sharpest sharp thing you can think of. While felting, always watch your hands and fingers to avoid boo-boos. Make sure your pokes are gentle, too.

Step 3: Make two felt discs
Start with a small tuft of wool and loosen the fibers a bit
Place the tuft on the foam and gently poke the needle into the fiber. (Gentle pokes work best. The business end of the needle is only an inch at the tip. Poke any further than that and it’s a waste of your efforts.)
Pick up the disc, flip it over, and poke some more. (Flipping often keeps it from permanently sticking to the foam.)
If the disc is about the right size but it isn’t as thick or as strong as it needs to be, pull a little more roving, loosely wrap it around the disc and keep poking. Repeat as needed. (For this project, the final discs should be about 1/8" thick.)
It's fine and dandy to have a little bit of fuzzy around the edges of the disc. You'll be able to use that to connect the discs together later.
Repeat the whole poke-y process and make a second disc... go, go, Felter!
Step 4: Sew a conductive patch
Thread the needle and tie your favorite knot at the end.
Stick the needle into the center of the disc and pull it through about 1/2" - Sew into the thickness of the disc, but not all the way through to the other side... like a tunnel that begins and ends on the same side of the felt.
Pull the thread through so the knot is snug in the center of the disc.
Insert the needle again near the knot, using the tunnel technique I
Step 5: Connect the connector
Insert the needle into the disc near the last exit point and pull it out about 1/8" from the edge, using the innovative, future-shattering, patent-pending Tunnel Technique™ as mentioned in step 4, in the past.
Slide the needle through one side of the ring, hold it in place on the disc so that the other side of the ring sticks out, almost over the edge of the disc, and secure it with little stitch. Keep making stitches through and around the ring until it's secure and snug enough to stay put but a little flexible so it moves with ease when you wear it.
Step 6: Accentuate the (+)
I'm going to make a small white dot to mark the + eye ring.
Take a tiny wisp of fiber and roll it into a loose ball. Anchor the ball to the center of the flower with a few gentle pokes.
Gently poke the edges of the dot towards the center. This will make it even more secure while creating a puffy shape.
When the dot begins to take shape, use very gentle pokes all over it to felt the surface without flattening the shape.
Step 7: Embed the Battery
Gently poke around the edges of the disc, securing them together. Flip and continue working around the edges with tiny, deliberate pokes.
To clean the edges and further secure the discs to each other, turn the lightly-assembled battery holder on its side and gently gently gently poke all the way around.
Repeat these steps as needed. Poke as closely to the edge of the battery as you can in order for it to stay in one place and not go sliding about willy nilly.
Step 8: Test and GO!
Use the alligator clips and see the light!
I've not done this yet but I had an idea: what if we had lobster clasps on each side of this holder instead? That way, you could make multiple necklaces for yourself and switch the battery pack between them freely.
