I'm planning on doing mine assembly line style. I had 2 yds of wonder-under left from when I was a girl scout troop mom (long story, my mom was leader for my sis' troup, and the co-troop mom got in an ugly divorce, began binge drinking, and dressing like britney spears at 50... at scout meetings). I'd just turned 18, and became the other brownie "mom" as none of the other parents wanted to and you need 2 adults to run a troop. The girls did a charity quilt for the children's shelter in town.
So I'm tracing 24 combs next to each other, to figure out how much red to buy, then feet, then wings, etc. Since my math skills are iffy I'll trace each part, measure out how much I need based off that, and go shopping. It's low tech, and probabilly the slow way, but it'll work.
