I want to attach a bunch of patches (like band patches) to the back fabric panel of my wheelchair. The material is this water resistant black fabric, it kind of feels like a windbreaker. I think it'd be cool to cover it with the soft half of velcro and then attach a couple squares of the scratchy velcro to the actual patches. That way, if I get more patches in the future or I decide I don't like how they are arranged, it's really easy to change. My dilemma is that I'd rather not attach the soft velcro directly to the wheelchair back (it's really hard to detach the velcro because the adhesive works so well), so I was wondering if anyone had suggestions on how I could make a removable cover for the back panel that I could attach the velcro to? I know this isn't a craft community, but I figured there were enough people here that someone might have some ideas. Thanks in advance, I really appreciate it.
