That is the best idea yet that I have seen for holding rulers in place. I have tried putting and old iron on it. Which works but the cord bugs me. I have the handle, I don't like it, becuase it gets in the way of the lines. I have tried the not slip plastic backing, Ok...not. The sandpaper works the best, I use really rough grain I get from my husbands workshop. I am going to get a clip like yours.
