I opted to buy the DD today. I looked at Creative Grids triangle rulers; they're $20. They do have lines on them, so one could cut a smaller triangle. But I can draw my own lines with a Sharpie! As long as I was ordering the DD, I ordered the Glorious Hummingbirds Layer Cake. Not sure if I'll use the wedge on that, but I've been wanting the hummingbird fabric. There are several fabrics in the charm packs & layer cakes that are not available in yardage. JCY
