I got the inspiriation* from a Martha Stewart tutorial, then changed it up to fit my family. Getting the goatee right without turning my husband into a giant bobble-head was the toughest part. I used graph paper snitched from my husband's science-stuff stash and my daughter's crayons to plan it all out, then used some large-blocked cross-stitch fabric to make it easier. I could do about one item per naptime - a Bears sweater, my curly hair, a much-loved purple blanket. The Great Dane took two naptimes.
Contrary to my memories of learning how to cross-stich as a child -- and then refusing to cross-stitch as a child -- this was actually pretty fun. I might make another one, if I can pick an appropriate subject.
*According to the comments section, Martha got her inspiration from an Etsy seller, but gave no credit. I have no idea.
