I have just finished HQ my first queen size quilt. It is a beautiful pattern called Blue Willow, all 12 white on white squares with 12 different blue designs. White and blue sashing w/9P. The next quilt, for my older daughter, same pattern, but with southwest colors in the squares (gee I wish I had a picture). I bought varigated thread and now I can't decide whether to hand or machine quilt. Please help!
