I was searching the internet for Yo Gabba Gabba craft ideas and found that on NickJr.'s website they have IRON ON TRANFERS! Wow what a find! Here's the link: Brobee Iron-On (they have all the characters on the website). This is what I did with the transfers (and I made a fleece throw too!)
Here's the throw I made: Just bought the fleece (at Menard's for less than $2.00 each) and cut out shapes in felt, then sewed them on, and DONE!
