Anthony - it is hard to tell just how long it took. It was one of those pick it up work on it for 10 or 15 minutes and then go do something else for a while. Plus I got quicker burning the texture as I went. If I had to guess I would say between 4 to 8 hours of burning, but I could be off.
Anthony and Dario - I have practiced quite a bit trying to burn my signature but have never been happy with the results. I will continue to practice since that is what I bought the pen for in the first place, but I have my doubts since most of the signatures I see burnt on I don't think look very good. MY signature looks bad enough with a pen [B)].
