I recently learned about a ruler called the Folded Corner Clipper, a handy tool for when you need to sew squares on corners. There is a quarter inch seam allowance and ruler markings that when all in alignment, give you very accurate blocks. You line up the ruler with your pieces of fabric, and use your rotary cutter to trim away the excess fabric. Then you use your quarter inch foot on your sewing machine and stitch away.
I ordered one immediately of course. I always do that.
And when I got it, I thought "Hmmm". Maybe I already had something that did that exact same thing. I tell you, sometimes you can just shop at home and save yourself some money.

And corner clipping with the Easy Angle ruler.
After working with both rulers for a few hours, I have to say for corner clipping, the markings on the Corner Clipper are slightly easier to read. I do love this method of sewing corner squares. Instead of marking with a pen, sewing, then clipping off the corner, with the Corner Clipper (or Easy Angle) you eliminate the marking step and just cut and sew.
The Corner Clipper is a terrific little ruler. But if you already have an Easy Angle ruler, possibly you don't need to purchase both.
