You position them on each side of the butterflied seam. I leave them there and take them out just as I get to the intersection.Perfect square, and if you pick out a couple of stitches it lies really flat when you are pressing your block so you don't have the bulk. Are there some of you that know about this helpful hint?
Practically perfect in every way. If you haven't used these pins before I highly recommend them. I mention these at every quilt class I teach. And there is always a great demand for them after class at the shop.
