I wanted to reuse some jeans that no longer fit and so I just dove in.... I don't have a lot of sewing experience, in fact, I've used my sewing machine three times before this project, just to sew some straight lines (they weren't straight). I cut all the legs and sewed them together then took some canvas-type-cloth I had and made like a mini duvet cover with ties for a chunk of foam for the 85lb pup- Fender. I didn't really measure, kinda eyeballed it but he seems to like it.
