OK, I picked up a pinking blade today at JoAnn's, but didn't realize that the regular cutters aren't designed to work with the special blades. Oh phooey! I was able to limp along (the blade kept falling off!) and pink a few more fabrics, but I'll plan to run back to JoAnn's tomorrow for the appropriate cutter for this blade. Even though I'm going to end up spending more money than I intended, it still is way quicker that using pinking shears, and it does save all that time trimming raveled threads.
