The Double Square Up by Quilt in a Day

Finally, a ruler that lets me square up half-square triangles and quarter-square triangles with the same tool — the two-in-one design saves so much time. I can switch from one block type to the other without grabbing a second ruler.

The half-inch markings on the top portion are exactly what I needed for trimming my half-square triangles accurately. It’s so much faster than juggling two separate rulers.

I was tired of switching rulers for different triangle blocks, and this double-ended design saves me so much time. The 4½" top half squares up my half-square triangles perfectly every time.
