I bought these to add a finishing touch to wedding panels and found them easy to apply and redo if misplaced. I used the tip of a knife to poke under the edge to finish these and they immediately peeled away from my acrylic painted wood surface. Although easy to replicate, it was still secured very well and would not come loose. I'm deducting a star because it seems certain letters are disproportionate. The designers probably used statistics to figure out how much of each letter to put in, but in some cases it seemed absurd. For example, there is a huge amount of E's, but only a few 5's and 3's. Because of this, I had to purchase additional sheets to complete my project, although I won't mind additional letters in the future.
