If you use 2 - 2.5 inch strips to make your tube, when you sew 4 squares together they come out at 10.5" unfinished. I'm going to experiment with sewing 3 - 1.5 in. strips together and see what they come out to. Geesh how I get side-tracked when I have other things I need to do. But I love to do new things. I guess I'm scatter brained. Does anyone else feel like this? Is this why I have so many UFO's? I have so many blocks that have never made it to completed quilts because I get side tracked.
