Didn't mean to leave you hanging, but I haven't been feeling well and had a lot going on in the evenings. I've actually sold the big one, but I still have a smaller one that it's just as pretty. It's about 2.5"x 2.5". I don't know really how to get a piece of it, other than just cut it off with a knife or something.
Where are you located? I'm in Georgetown, just a little North of the outlet mall in Round Rock.
