I won mine on an ebay auction. 100 for 5.00 + shipping. I ended up with three sets. I love to use them on my bindings. I will clip the whole binding, let it set for a day and when I hand stitch the binding the next day the binding lays just perfect when I stitch. Makes the hand stitching go a whole lot faster for me anyways. Seems to give the fabric a memory to lay over and makes the fold easier to make.
