Here it is - Duet Doily from The Tatter's Treasure Chest by Mary Carolyn Waldrep. I made a couple adjustments, but I'm really happy with the end result. It is done with size 30 thread and measures about 9 inches across.
I've also made progress on the plans for my dresser scarf. I remembered that I had a piece of white linen that a co-worker brought from Ireland several years ago. I checked, and it is the perfect size, so I trimmed and pinned it and have begun working the hemstitch edge. Then I will figure out an edging and a painted design.
