For one thing, all Build-a-Bear animals are not created equal, as in they vary a surprising amount in size — specifically neck size. That made drafting up this simple pattern a little less simple. Then both my sewing machine and my serger decided to get fouled up on the same day, causing me to complain dramatically to my husband that the sewing universe was conspiring against me. But once I finally got the pattern figured out with an adjustable neck! This really is a pretty easy sew, and it should fit most Build-a-Bear sized stuffed animals pretty well.
