I remember someone writing about them and someone sent a pic. at wal mart yesterday , I was looking thru their knitting stuff and now they have one by Boye that is a rubber like material and it has 3 different tops that you snap on top to carry your thread thru. It has little loops to carry yarn thru and it is for different size yarn Wish I could send pic because you know I had to buy one Thought anyone that does different color of yarns at a time might be interested in it . I bought it to see if it would help me get use to doing continental since I can't seem to get the hang of it . I can understand the concept of it but yarn keeps slipping off my fingers so tension is all over the place. .
