Not sure you understood. Aside from the fact that I don't own a single pair of bike shorts, the issue is the cloth-on-cloth rubbing. It bugs the hell out of me, because I feel like I can't move around enough on the saddle. Also, I have a couple guitar straps that are "garment leather" on both sides...obviously this is done by sewing two pieces of leather back-to-back, but the end result is a very comfortable strap that doesn't grab my shirt.
