I like to save cereal boxes, junk mail, toy boxes, and scratch paper to use as backings for the tape patterns- going to throw it all away in the end anyway, might as well get some use out of this stuff before then.

It takes a while to figure out where to cut darts in your patterns... if you mess up, you can just repair the cut with more tape and try again. After a while, you'll just "know". My headcovers follow the same consistent formula of shapes in general, except on critters with a drastically different facial shape from the norm.

Keep the pattern pieces while you're working on the headcover, if you ever get confused as to how certain pieces fit together, you can just refer back to the markings and notes you wrote on the pattern itself.
