I am presently working on the "Over the River and Through the Woods" by Crabapple Hill. I use muslin and baste the two layers together so they don't get lumpy while I'm doing the embroidery. Like QltrSue I used the Sulky 12 wt. thread - single strand Charcoal. Loved it. Almost time to start the blocks - the hardest part is over. Good Luck with your project.
