I agree that breaking out the sewing machine may be more that what many people are willing to do. I was just noting that if you want to use a thicker, sturdier, longer-lasting material and are worried about the material bunching or indenting the foam beneath, sewing is the way to go. I attempted going without and I just wasn't that into it. After sewing it, I was completely happy. I also wanted to make new grab straps, since I was using a different black vinyl and also the red so I knew I was going to be sewing anyway. As for the contact adhesive, I fully believe what you're saying. That's some good stuff... but like I said, the staple gun worked for me and was much easier than adhesives.
