Going to the Sewing Expo (Puyallup, WA) can be dangerous! You get mind overload of all the 'new' and latest gadget. Sometime they make our life easier and other times we purchase items that just sit in our drawers or on our shelves.
I have made my prairie points with a square piece of fabric, folded twice. A class that I took this last weekend on boarders, suggested for scallops ~ EZ scallop rulers.
