Good suggestion Carrie--I was thinking about using some black and white fabrics as they have "generic" (aka Holstein) cows--but don't think I have 50 pieces in my stash, plus this is on Sunday and today is Tuesday. My mind was rattling with ideas when I was in the field yesterday. Thought of doing a crazy looking cow outline with said 50 fabrics. Of course could use 50 fabrics of any kind. Also thought of making a EPP triangle quilt. Just found this on Pinterest. I have the book most of these cows come from okay off I go!!!!!
