DESCRIPTION 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! You’ve got X-Blcks! It’s that easy.
