For any of you Tatters out there in Tat-Land who are tackling The Monster, I have a suggestion for the 9-picot reverse rings in the final row.
The first few of these rings I tatted did not lie flat, and they closed with a bit of a rollover effect.
So, I tatted 2 ds at the beginning and at the end and then POSTED the shuttle. It worked well. It is obvious to me in the photo. Perhaps you can also see the difference. I am pleased to have discovered this fix early.
