I've made 2 Dresden plate quilts and I just eyeballed!! I did the sew and turn and appliqued down. If I'm off a bit you would never know. When I get to my MIL's house I'll take a pic and post it. One of those quilts done before digital cameras!
Happy Thanksgiving everyone!
BTW: I slept under my avatar quilt last night at my daughters with that cutie quilt inspector beside me!!
