when I was (more)broke and couldn't afford a 'real' binder, i made my own with ace bandages. While wrapping them around yourself isnt a good idea, you can cut and layer them to make large panels (front and back) and then stitch them up the sides. I used 2 in total, with one being wider. I took two lengths and lined them up along the edge, and used a vertical looping stitch (totally not a technical term. I stitched it that way so that when it stretched the thread didnt rip, it went diagonal.) then i stitched another length along the middle the same way. It made a 12 inch panel with a stronger elastic in the middle. Repeat and sew along the sides. Tube-top style. It worked for the time, it was hot though. if you make one like this, measure the fabric while its stretched but leave a little stretch, so you know it wont be too tight. always make sure you can easily take a deep breath with any homemade binder. (I also used that jean pattern. works well, but you have to be careful not to tie it too tight) good luck man.
