Sadie, I seem to always dent the back of my bows, but it is easy to fix. Get a dish rag or paper towel or whatever is handy and undyed, soak it in water. Heat up a piece of metal about the size of a butter knife handle(just the end of it) to slightly red. Fold your wet cloth a few times and place over the dent. Now press the hot metal in to the wet cloth directly over the dent. This will force steam into the wood and raise the dent. Sometimes it requires several applications. Just be sure to not touch the metal directly to the wood. Give me a call if you have any questions. Josh
