The Wiggles Cotton fabric

We are in need of a minimum of 1 yard of The Wiggles cotton material. My family runs a non profit organization making personalized quilts for children with cancer and we currently have a pediatric brain tumor patient who would like a Wiggles quilt and we have not been able to find cotton wiggles material anywhere. You can visit us at www.caringbridge.org/visit/quiltsofhope
Thanks for any suggestions on where to buy this.
