During the summer vacation I joined the Great Granny along, but since I was far away from my sewing machine I had to wait until I got home to make one. There is a link to this sew-along on my blog.
I started making my first block yesterday, but instead of cutting the squares 2.5", I cut mine 1" square. The original square was approx. 12" finished, while mine is approx. 3.5". It was interesting making this mini, and I finished it as a mug rug/coaster. The plan is to make several more in the same style.
