I wanted to make my own pfd (personal flotation device) and started out with two warning vests (they are compulsory to have in the car here in Europe, $5 apiece). I sewed the two vests together around the neck, shoulders, armholes and down the middle and sides, creating pockets for the flotation material.
As I had some styrofoam already, I used that and cut some pieces to fit into the pockets. I had to do it in segments, because the styrofoam is rigid and doesn't follow the curve of the body. After inserting a segment, I closed that pocket by sewing. The pieces at the top near the shoulders are thinner than the ones at the bottom for comfort. When I was nearly finished, I had the idea that a camping foam insulation mat would be much better than the styrofoam, because it is pliable and you could insert it in just two big pieces left and right, maybe glued up to three or four layers depending on the thickness of the mat. (I continued with the styrofoam.)
I then added a zipper at the front, some belt loops and a bottom strap, all from material I found at home. A luggage belt ($2.50) serves as a waist belt.
If you wanted to add more flotation, you could easily add a big piece of foam mat to the back. Lift with these styrofoam pads comes in at around 5 kg (11 pounds) which should be ok. It is a swimming aid and not a life jacket after all.
Cheers
