I love log cabin quilts. I'm making a scrappy courthouse steps right now for a queen bed in 1 1/4" strips (before sewing) and it's so relaxing and unstressful just to sit and sew without hardly thinking. It's almost like meditating. I don't measure, just cut my strips as I go to square it up. So far, no problems with block sizes. They are taking me about 15 minutes per 7" block, but I'm pressing as I sew.
