In case you haven't heard, Heather's Tatted Ladies book is now available. See her blog or etsy shop for details.
I got to test tat one of the twelve patterns while the book was in progress. I found Heather's instructions easy to follow.
This design is Lady Shauna. The one above was worked with size 20 Manuela dark green and Valdani size 12 variegated. She is about 5 1/2 tall. This version was worked with Oren Bayan size 70 brown and a vintage Coats yellow variegated. This one is about 3 1/2 inches tall.
