Check out Salado Arts Workshop http://www.saladoartsworkshop.org/ I have been teaching there recently - had lots of fun with the hearts for Valentine's Day. Come see us for Easter eggs on February 27 and 28th!
I took a class recently at Blue Moon Glassworks in Austin. The teacher was Trey Cornette and I had a blast. He is a wonderful teacher and I learned bunches. If you ever get a chance take a class from Trey - at Blue Moon of course!
