Part I is in previous post.
After the first corner, pattern repeats the side part with two ecrù rings and the coloured trefoil:
It's always there to bother, the gap between the first ds of the chain and the last ring. I try to use my middle finger of the left hand to get the first half closer, then keep it in place with thumb and forefinger and tat the second half. This works for me. I don't care too much about the core thread in this point, because then it will be pushed in place with the rest of the chain.
The second corner, with the coloured ring of 10-10 joined to the trefoil:
The third side is always the same: 2 rings ecrù (5+5+10-10 and 10+10-5-5) and a trefoil (10+5-5 then 5+5+(to center)5-5 then 5+5-10).
After the 3rd corner, while tatting the last ring in the trefoil, don't forget to join to the very first ring in the first trefoil:
Then remember to join the last ring in the last corner to the very first ring tatted in ecru:
The last chain is tatted normally but I learned - and love - this method from Frivole (thank you very much!) to hide ends at the end:
She has got a great photo-tutorial in one of her sets in flickr, but I don't put inside both ends, at the end only the core thread is inside the last chain. I'm afraid ends would pull out. I hide the other end with the help of the magic trick loop that I put in the start ring. At least, there's only one end to hide!
I finished, and you?
