I gave the glass etching kit a try. I'm not sure if you just did first initials, all initials, or names. The hardest part is getting the letters lined up because of the curve of glass....but it's worth it! I'm sure the girls will love it!
Not sure what to do for my 13 year old BM....I'm thinking maybe a pilsner glass with her name on it, so she can drink soda and stuff out of it?
