Fortunately, there’s a way to make four quarter square triangle blocks at a time without having to cut or stitch triangles. Plus, you can easily use this method for any block size – which means it can be used for just about any pattern that calls for quarter square triangles.

The tutorial, from Sherri at A Quilting Life, walks you through all the steps. You start with squares of fabric in the right size. According to Sherri:
“To make 4 quarter square triangle blocks, start out with four squares of fabric that each measure 1” larger than the unfinished size of your desired block. So for a 4″ unfinished block (3 1/2″ finished) you’ll need squares 5″ x 5″.”
After that it’s simple sewing and cutting.
