Fasteners other than Hook and Loop I am looking for fastener options to attach 2 fabrics and also keep them detachable. I am working on an adjustable knee brace so small hook and loop patches are a good option but they are difficult to sew on. So, I have also tried snap buttons that can be easily punched instead of sewing but they are usually metal or plastic. I want to avoid hard material as falling on the knee while wearing the brace could cause extra damage because of the hard buttons. So, I am looking at different options like self adhesive hook and loops about which I am exploring in another thread. Just wanted to see if there are any silicone based snap buttons or some soft non metallic snap buttons that could be used as fasteners or any other fastener options that could be used. Laces are another option but they tend to open up.
You might consider using grommets, then lace it up. You can get a grommet kit for about $10.59 which includes grommets. They are really easy to install, and they actually look pretty cool in addition to their functionality.
