The 7 1/2 X-Blocks tool will give you a finished block size of 7. This template is the standard size used for bed-size quilts, lap quilts, and larger wall hangings. X-Blocks quilts start with easy to piece strips or blocks that are sewn together first. Place the X-Blocks tool on the strips or blocks, match the seams with the designated line of the tool and trim along the edges with a rotary cutter. Voila! Youve got X-Blcks! Its that easy.Color: ClearMade of: AcrylicUse: Quilting RulerSize: 7.5in x 7.5in
