Oh, I love to knit lace and I love handkerchiefs with a lace edging. The pattern is Project #6 and can be found in 'Heirloom Knitting' by Sharon Miller.
The picture shows 16 rows completed. Sharon got 3" for her width......I'm getting 4".
I'm using DMC Cordonnet sz 70 Coton and 5/0 needles. What is the blue tape for you ask? I didn't want to make a couple of my dpn's a permanent set of straight knitting needles (by gluing beads on the ends) and the blue tape will come off easy and leave no residue.
I found them and my 6/0 needles at Victorian Cottage Treasures. They even carry 8/0!
I used to, as a kid, knit with safety pins and sewing thread so this is nothing new.
