I'm also working on ideas for a new makers mark stamp. Currently I use a stamp with my initials that I designed. I really want to have my last name on my work so that someone would know who made the piece. Here is my current stamp, it is also too large to put on many items.
Here are some ideas. What do you think about the font? Should I stick with the one that I already used before? I designed that one, and do like it. I found a website where you can design your own font that you upload into their website and then download onto your computer. I might try that too. It would be pretty cool to have your own handwriting as a font!
