Hammocks are great fun. When out hiking or backpacking, it's a great feeling to take a quick nap suspended in air above the sharp rocks, on a steep slope, or even over a stream (yes, I've done all these). Plus, they're an excellent way to relax on a lazy summer day in your backyard.

But hammocks either cost money or take time and effort to make. There are a number of solutions to this problem – here's one possible method. This design can be done in an hour for around $10. This would make a great scouting project. If you want a compact, easy-to-build, cheap design, then read on.

And don't forget to vote for me in the paracord contest!

Step 1: Materials

The following materials should be readily available in your local community.

1 piece of fabric, 9 feet in length. You can either buy it at your local Wally-World (look at the bargain material at $1.50 a yard) or you can use a bedsheet. Fabric strength is not really an issue, so pick whatever material you like best, provided it's at least 48” in width (60” pieces are more comfortable).  I prefer non-stretchy fabric, but feel free to experiment.

2 carabiners. I found these at my local Home Depot at a dollar apiece. They say they are rated for 150 lbs. While I wouldn't trust them with my life, they hold up just fine for suspending me a few feet off the ground. If you'd prefer something beefier, try stainless steel quick links. They weigh more, but are rated to much higher safe working loads.

35-45 feet of paracord. I know I'm going to get some flak for this one, but in my experience this stuff is strong enough for the way I use it. If you don't feel comfortable trusting your weight to 550 cord, climbing rope can be substituted.

Additionally, you'll need a pair of scissors or knife, and a lighter (optional).

Weaving three smaller rated cords together would give a stronger "cord", but with a slight increase in cost.

For a lightweight hammock for backpacking order a very cheap nylon tablecloth form Tableclothsfactory.com. The edges are finished and they come in various sizes and bright colors

I love the ninja flip. For sure going to make this. Thanks

hey man GREAT ible great idea and great video. (taught me some knots aswell )
one question though. how small does it fold/roll up into ? (just roughly because i know material thickness etc will be a factor)
depending on that will be whether i make it. definatley a great thing for a camping bed and easy to untie for a makeshift shelter aswell !

Love this!

And I think I have all the materials already! =)

To avoid marking or damaging the bark of the tree you should use tree hugger slings. A separate about 40mm wide sling to wrap around the tree and then tie your cords into these slings.

Great idea! I have been wanting a hammock for camping, but I don't want to spend the $50+ for it. The information was simple and very easy to understand. I will be making this very soon.
justintime516 says: Jul 22, 2011. 9:17 AM
Hey paco, really great 'ible. I decided to double the paracord and use climbing carabiners to make myself feel even more comfortable. Also, instead of using a bed sheet, I used black ripstop nylon. This unfortunately called for a small amount of sewing to clean up the edges, but no more than what a 17 yr old guy could handle. I did use a slightly different knot to tie the ends of the hammock up, as it looked a bit tidier (forget what it was called). Thanks for the great idea again!!

p.s. here is a picture of my hammock. I was too lazy to find trees in the woods and deal with bugs, so I simply hung it on our swing set for now.

Cool Instructable. Seeing as I weigh 220 I'll probably spring for some stronger carabiners and maybe double the amount of paracord.
Zex_Suik says: Dec 25, 2010. 5:57 PM
Great 'ible! Very practical and easy to make. I'm a big fan of 550 cord (paracord). It's a must have item in all my tool kits.

I really like the idea of the knots. Makes sense

I am an engineer so I can help you a little with your tension calculation.  Assuming the weight of the rope and hammock are negligible compared to your weight, then you have to divide your weight by the cosine of the angle of the ropes make with vertical.  The tighter the hammock is between the trees, the more tension will be on the rope.  At 170 pounds you would have 85 pounds each on the ropes if you hung vertically from the branch.  85/1.00 (the cosine of 0 degrees) = 85 pounds.  When you stretch them out to 45 degrees you have 85/0.707 = 120 pounds.  If you stretched it to 60 degrees (more comfortable to me), you have 85/0.50 = 170.  If you could tighten it to 85 degrees, the tension in each rope goes way up to 975 pounds.  Your little aluminum "keychain" carabiners would be wide openb at that point. 
pacowarabi (author) in reply to dchall8Apr 12, 2010. 1:03 PM
So this is why slackropes have to be extremely strong.  They are trying to get the rope as close to horizontal as possible, thus increasing the tension exponentially.

Thank you!  I've been trying to understand this aspect of hammock physics for years, and you finally explained it in a method I can understand!  So my design is already pushing the safe working limits of the carabiners.  Oh well -- I haven't had one fail in 3 years of using them, so I'm not worried yet.
jeffconnelly in reply to pacowarabiApr 18, 2010. 8:10 PM
 The safe working load is VERY different from the breaking load. I would guess that each of those carabiners could easily hold 300+ lbs.
thatbellevuekid in reply to jeffconnellyAug 3, 2010. 5:43 PM
I had a friend put 600 pounds on one of those aluminum carabiners once! It was bent at that point, sure, but it never broke!
pacowarabi (author) in reply to thatbellevuekidAug 3, 2010. 6:37 PM
Heh. Thanks for testing that for me! I knew those carabiners could hold! Once again, not recommended for rock climbing, but they're fine for hammocking.
pacowarabi (author) in reply to jeffconnellyApr 18, 2010. 9:21 PM
Yeah, you're probably right. There's a reason that they call it the "safe" working load, but then again, we're talking a hammock, not rock climbing equipment.  The very worst case scenario for catastrophic failure of one of the components is a broken arm.
bowmaster in reply to pacowarabiMay 30, 2011. 8:01 AM
Or hitting your head and dieing.
Shemagh in reply to bowmasterJun 23, 2011. 8:40 PM
Unlikely from hammock height.
dchall8 in reply to ShemaghJun 24, 2011. 9:01 AM
Some people hang hammocks high in the trees, some hang them across rocky areas where tent/ground camping is impossible. I've even seen one hung across a creek. For these applications you would want rock climbing rope and hardware. For the average backyard hammock, you can get away with a lot lower quality materials.

HiIlariouse!!!!! Your cable cam was funny!! how does one vote for you for the paracord contest or is it too late?
pacowarabi (author) in reply to daliaislearningJul 27, 2010. 9:25 AM
I'm glad you liked it. Unfortunately, the contest is over. But tell all your friends about it -- I just like the views!
beanblog says: Jul 20, 2010. 11:34 AM
Good stuff! Made one out of a kind size bed sheet and it was big enough to allow me to completely cocoon myself inside at night. I took it on a minimalist hike/camp trip over the weekend and it worked great! Much lighter than lugging in a tent/air mattress/etc.
pacowarabi (author) in reply to beanblogJul 20, 2010. 2:11 PM
I think the way to go for the minimalist approach is the bed sheet. You don't have to worry about sewing or fraying, and you can pick one up anywhere or just use one you have lying around. I may have to pick up a king size sheet. That sounds comfortable!
impulsegordon says: May 19, 2010. 3:08 PM
for an easier dissasembly you can also use a marline spike hitch after you do a round turn on the tree then when you r done you just pull the spike and wala! instant dissasembly.
pacowarabi (author) in reply to impulsegordonJul 20, 2010. 2:07 PM
I've thought of using a marline spike hitch, but was worried about it slipping over an entire night of sleeping. Maybe I'll have to experiment and see how it works.
mayo291 says: May 15, 2010. 6:15 PM
 This hammock is sooooo comfortable.  Thank you for making this 'ibble.  I made one today and i used a queen sheet folded in half and i works quite nicely.  Keep posting paco!!!   : )
BrantFlakes315 says: Apr 21, 2010. 4:57 PM
 I made one with a twin sheet, then decided I wanted a bigger one. I loved the king size, but after I used it twice, I heard a small rip as I sat down. Looks like the sheet is the weak link in the chain. I'm thinking of just buying a parachute hammock because they aren't too expensive.
SureShot says: Apr 16, 2010. 10:05 PM
What an awesome idea. Thanks for sharing:-)
tictaclad says: Apr 14, 2010. 9:57 PM
 i just made one...awsome! but my bro is kinda big and ripped the sheets...any suggestions for more strength?
pacowarabi (author) in reply to tictacladApr 15, 2010. 6:54 AM
How did he rip the sheets?  Was it along the seams?  In the middle?  Were they thin sheets?

It's hard for me to imagine someone ripping the sheets.  That should be the strongest part of the design, as your weight is spread out over a large area of fabric, and where they connect to the paracord, they are bunched into essentially a very thick rope.  Unless the sheets were very thin, old or already had a flaw in them, I really don't know how that would happen.  I used some very thin material once (I could almost poke my finger through it) and although I stretched the fabric, it didn't tear.

The other option would be to go to Wal Mart and spend $4.50 on 9 feet of thicker material.  Sorry -- I didn't think that was going to be a problem.
tictaclad in reply to pacowarabiApr 15, 2010. 6:26 PM
 down the middle..,..but thanks for the suggestion
Hoopajoo says: Apr 11, 2010. 9:23 PM
Re: Tree damage
I usually place several dead branches between the tree and my ropes. This way the tree is untouched by the ropes and my hammock is just as secure. I leave happily rested and the tree leafs happily.
pacowarabi (author) in reply to HoopajooApr 12, 2010. 10:55 AM
That's a great idea.  The dead branches disperse the weight and any cutting happens to the branches instead of the tree.  That eliminates the need for carrying extra weight as padding.  Thanks!

One question -- how many branches do you generally use per tree?
Hoopajoo in reply to pacowarabiApr 12, 2010. 5:19 PM
Depends on the diameter of the tree. Generally enough to keep the ropes from touching the tree where they're spaced apart. If the rope touches the tree in a place, add a stick there.
vadios in reply to HoopajooApr 15, 2010. 4:22 AM
I think 2 pieces will be quite enough for this. BTW the rope wont wore down as quick as without branches! 
BrantFlakes315 says: Apr 13, 2010. 6:34 PM
 I've always wanted a hammock but never wanted to bother paying 30$ for one of those parachute material ones. This is perfect! 
(the physics lesson was an added bonus too)
pacowarabi (author) in reply to BrantFlakes315Apr 13, 2010. 7:24 PM
I love mine.  And it's so much more fun to build it yourself than to use a store-bought hammock.
