I have been trying to figure this out also. I painted several plaques for family but was never satisfied with my lettering. We even checked on those "rub ons" but the letters are not very big. I don't really want to put vinyl on it but I am not sure what options I have besides that and painting. I don't have a cricut machine...and really don't need one for anything else that I do.
If anyone has any suggestions...that would be wonderful!!! I guess I could print out the letters and then do the tissue paper thing or cut a stencil for it.
