Phantomfett, I've used sticky back velcro before and sewed over it too. Problem is my thread also gets sticky, and gets stuck, and I wind up with this giant glob of stick thread all knotted up! They don't do this with the industrial velcro, but there is velcro that has 1/2 stick back and 1/2 non sticky and I 've used that before- works very nice and no sticky needle!
