In my experience, stick on Velcro does not hold. I have even tried the industrial type, and had to either sew or staple it to whatever I was using it on. I was afraid to try sewing it, but once I did, and realized how easy it was to sew, I use it a lot now. Iron on did not stick any better for me. Sewing through the adhesive just makes a nasty mess on your machine and the needle, Cost me a brand new Schmetz needle to learn that. No adhesive for me.
