Renulek's "Spring 2014" napkin (what I would call a doily, mat, or - if it gets really large - a centerpiece) is posted on her blog. She gave the pattern for the center on Monday, 10 February (2014) and the second round today (Tuesday, 11 February). This is such a pretty, lacy bit of tatting I really couldn't resist.
Here are the first two rounds, done in Sulky Blendables 12-wt cotton thread. Color is #4022, Midnight Sky. Sulky #12-wt works out (for my tatting tension) to be about equal to a size 80 tatting thread. It is intended for quilting and machine embroidery, I think. It is softer than 'the usual' tatting thread, but I love the colors and the 'feel' in my hands. Picking out mistakes can be difficult, not just because it's tiny, but because it is more loosely twisted than a thread made specifically for tatting. I can hardly wait for the next round.
