The last round has 20 separated motifs, I'm enjoying this round a lot! There was a false start, as I made picots longer than the necessary and the first motif cupped. I cut the first gauge in half (oh, don't worry, it was just a small plastic slice) but was not yet perfect. After smoothing the plastic with a nail file, the third motif was perfect.
Absolutely slow tatting, but I like very much this doily. In case I want to tat it again, I should remember a lesson learnt when I tatted the "Mary Maynard's small doily" (http://www.georgiaseitz.com/2009/marymalltathplacedoily.html), that is - in that doily - the round with hairpin lace rings is tatted before the centre and left open till the last repetition of the centre, this prevented the bigger round to twist and joining picots was easier.
In Burda's doily, the rounds with block tatting are made first, then you join them and previous round with a next round (that is block tatting isn't directly connected to previous round but "trapped" by next one). It would had been far better if I had left the rounds with block tatting opened till the end of next round, in that case I wouldn't have had one block upside down and a chain twisted.
What's all this about? It is that now I understood why they wrote"TWO tatted doilies" as a title over this pattern! (Implicitly saying "do it twice, the second would be better"?). My opinion: not at an "Intermediate" tatting level, even it is "just" block tatting.
