In the previous post there's how to tat the central part; it's not really a two rounds pattern because the inner part flows into the outer part. For me SH1 is the green thread, SH2 the orange. Sorry for the bad quality of these photos, orange became red!
My gauge with size 80 thread is 14ds per centimeter.
Coiless safety pins are very useful as stitch markers too, but I feel as I can't tat block tatting in the same way without them. I put the pin just after the last ds in the first chain of block tatting because I needed a picot exactly there.
I took the pin out at this point. Lock join with SH1.
And then... to be continued in the next post!
