I had a lovely email today bringing me back to a technique I taught at last year's Palmetto Tat Days.
I heard from Claudia de Formosa, who's in Argentina. She has two lovely blogs on tatting - one for her own tatting, one for teaching. Both are in Spanish, but her pictures are so very clear that you don't need to know the language to understand them.
Claudia asked me about stacked dimpled split rings. I taught how to make stacked dimpled split rings last year at Palmetto Tat Days 2011, and also mentioned them on my blog.
Claudia didn't get to come to Tat Days, as it's a looonnnggg way from Argentina and really expensive to come that far north. But she's a smart tatter - she figured out the technique by looking at my pictures!
