This ruler solves the common problems encountered when making quilt blocks with folded corners (also called snowballs, stitch and flip, or sew and flip corners).   

The ruler allows you to choose between two methods - making oversized folded corners that are trimmed down, or exact size folded corners with no trimming needed.  

No matter what shape you are adding a folded corner to (square, rectangle, or triangle), Simple Folded Corners can add them with ease and accuracy.  Comes with fully illustrated step by step instructions.
