Junior Engineers will love this Choo-Choo Dwipe. The bright, primary colors are eye catching against the black backdrop in this fabric. I have two of these available in this print. The Choo-Choo Dwipe has all the usual features. Please look at the sidebar to find out more information about my Dwipes! Feel free to email me or make a comment here if you are interested in this Dwipe! The cost is $15 which includes the cost of shipping to the U.S. and Canada.
