This is my first attempt at Mary Konior's glass mat, in her book Tatting with Visual Patterns. It was a challenge for me. First problem, I just used some cheap white thread, not singed. And it even had a thick spot. Every time I had to undo a ring, it broke. And I made lots of errors in the pattern. It requires good concentration. But, please don't be discouraged, if you want to make it. I'm on muscle relaxers for my back and I always watch TV when I tat. All that, and I can't wait to make another one.
