Triangle Trimming in a Snap

Wonderful tool that helps get those half square triangles trimmed just right. No instructions came with the items and that would have been nice as this was a gift, I wasn't sure how to use it and was not familiar with the product. It took some figuring out, but once I got it - boy was it slick! Just including some simple instructions would be so helpful.
