This is a cute one at Nested.
http://nested.typepad.com/blog/2007/07/materials-you-w.htmlI designed a bag hat I make for all the kid gifts. I call it the "Go Go art bag" Someday I'll get a tute put together for it!

sigh...
It is a combo of a crayon caddy and a tote bag. I've been making them for a few years.
Oh, I also saw a cute pattern for sale on Etsy..lets see if I can find it...
