I have had this America's Perle Cotton for a very long time and the Graceful Lace for about two years. Though the pattern works with lace weight yarns your hook size is a "F".
When starting this shawl, I felt the Graceful Lace (it is like a 00 lace weight) needed to double with another yarn.
and held it together with Halycon Size 10 cotton thread.
I have just started the last section and have 13 more rows to go. It is so pretty and a fun pattern.
The perfect accessory for chilly indoors during Summer!
