Here's a little example of what I do all day. The vendor sends in a sample, and it's my job to make it look like the character. I send in overlays, like the one below, and (hopefully) they send back something that looks similar to the drawing.
Here is a little concept I did for a plush sleigh, with Olaf hanging off the back. Unfortunately, the idea got canned, but it would have been SO cute.
The plush are available at http://www.disneystore.com and in stores, GO BUY THEM ALL!
