They are only sold at Hickory Hill Quilts and Sewing Center located in Hot Springs, Arkansas. They will do mail order but you have to call and place the order. (501) 318-2739 Monday thru Friday 10 am to 5 pm (CST). I just purchased the Large (finished size 3 1/2" ) and the X-large (6 1/2" ). I can't wait to get started. Thanks Eddie for this great tutorial.
