I realized as I was putting this workshop together that maybe not everyone is familiar with Build-A-Bear Workshop. First, I should say I am not affiliated with Build-A-Bear in any way. I have just spent a lot of time (and money) there while my kids were growing up. 
This is a store that has a variety of stuffed animals. They start out as just a husk with nothing inside. Part of the experience is watching them stuff the bear (or whatever you choose) in the store. 
That is where the idea for this workshop came from. 
Let's start building!
