I use my pinking shears all the time. I have 2 pair, one I bought myself years ago and a pair my mom gave me that I used when learning to sew oh-so-many-years-ago. I don't pink everything but usually do with cottons or other fabrics that will easily fray. I've not used them on any quilts but if I were to do another Memory Quilt I certainly would! Once the squares got out of my hands, they were handled buy a lot of folks and several came back very frayed...not unusable but it got trickey there on one or two squares. Of course, I'd do a lot of things different if I was to do another one!
