I love felt!  It is inexpensive and perfect for the beginner crafter since it doesn't ravel.  You can sew it, glue it or needle felt it together. 

Remember colorforms?  A creative mom to five children translated this idea into felt! You can see her creations at her etsy site:  http://www.etsy.com/view_listing.php?ref=sr_gallery_8&listing_id=17408633  She said a do it yourself pattern was on her to do list, but could be awhile before it comes out.  As a fellow mom of 5, I can understand that!

With a litle imagination–this (above) becomes this (below)!
