the red was a really thick piece of glass I used
we learned how to make cups last week and I got kinda gipped. this time we were in a group of 3 and I let the other person go before me since Tom had already made a cup and I wanted to be fair. But by the time it got to be my turn class was almost over and I only got to gather once. I ended up with a sorta-shot glass.
Tom's, of course, is nearly perfect. mine, not so much. BUT I do love my colors. Instead of using the glass colors everyone else was using, I used broken glass as my coloring.
