clover's bia tape makers are not (designed) by clover to make binding...they were created to make bias tape-people use for trim, embellishment, applique...they started making them long before the quilting craze took hold and quilters started looking for tools to make things easier- i have all the sizes of bias tape makers & really don't get how people use them for binding- since they are folded totally different- but that's just because i've never sat down with a prepared bias strip & tried to figure it out i guess. but---there is a difference between bias strips/tape and bias binding....2 different animals...i think simplicity has a binding maker on the market- it probably has the larger sizes-
