This 3D printed bias tape maker is specially sized and configured to accommodate jelly roll strips and Katahdin batting.
By forming the fold perfectly and holding the fabric in the correct position, you'll save up to a third to half the time in constructing your jelly roll rug. What's more, you'll get a more accurate and precise fold, so you can avoid the "cupping" that can creep into jelly roll rug projects. (If you're of a certain age, you know that hands can tend to get cramp-y doing this kind of work. Here's welcome relief!)
