By the way, ignore my rediculous sewing and try to do it better than me. I really, really suck at it!
Step 1: What you need.
1. An old t-shirt, sweatshirt, sheet or other scrap of material you have lying around (I used a t-shirt).
4. (optional) needle and thread.
Step 2: Shaping the Material
If using a T-shirt, cut off the sleeves, then cut up both sides of the shirt. Then, open out the flap and you should have a rectangle with the neck hole in the middle.
If using just a sheet or peice of material just cut it into a rectangle, proportions depending on the animal(twice as long and thrice as wide as the animal).
Step 3: Filling the hole (t-shirt only)
look at where the nec hole is. fold a flap of which was the back of the T-shirt over the hole and sew along the fold, closing the hole.
Step 4: Adding the loops
At both ends, use a ruler/tape and mark on every inch. Then cut at each one of these marks about 5 inches in. you now have nice frilly ends for your hammock, but unfortunately you will have to wave a solemn goodbye to half of these as you now have to cut off alternating ones.
Turn the sheet over so that whichever side you think looks best (the side with the pattern?) is now facing the floor, and the uglier side is facing up.
This leaves you with the same frilly appearance as before, except now there are less of them. Fold over each 5inch flap onto the sheet of material so that it overlaps just one inch. then sew these overlapping frills to the sheet, leaving you many lovely loops at each end.
The side which you have stitched the overlaps to is the bottom of the hammock, so turn it back over again.
Step 5: Erecting the Hammock
Another good point of the hammock is that it can be easily washed. just take out the strings, and throw in the washing machine!
