GO! Fabric Cutting Dies by AccuQuilt: Tumbler. Cuts one 6-1/2 inch tumbler. Tumbler quilts have long been a part of quilt history. Often these quilts were made with donated or shared fabrics and were known as Charm Quilts. This traditional shape has been updated by AccuQuilt with specially designed corners that make piecing a breeze. The die cut tumbler shapes align perfectly for nice straight edges on the top and bottom of each row. Simply add more tumbler shapes to the length or width to increase the size of your quilt. Ideal for both beginners and experienced quilters. Includes seam allowance. Use with the GO! Fabric Cutter (sold separately). Requires 10x10 inch mat (not included). Warranty: AccuQuilt GO!
