Iron-on velcro...I love it! I had never used it before and tried it today. It's fabulous! I've tried to use adhesive velcro and sew-on velcro and both are a pain in the butt. I read a post on another blog a few weeks ago and was inspired to try it. It works great. You just cut it, stick it on, and iron it on the reverse side for a minute. It works like magic. I had my daughter test it and she was pretty rough with it and it did not loosen at all. We'll see how well it holds over time but my initial impression of it is that it is great stuff!
