I added a picot edge once I was finished with my shawl! and I really like how it turned out.
This is my pattern and it was very easy to memorize once I set up the basic premise.
As I write up the pattern, I might make another one... : )
I think I'll make this a freebie up by my header like my edging and dust bunnies. It depends on how much translation from my short hand into sensible directions I'll have to do.
I did pin every picot edge which was a bit of a pain but as it turns out very worth it.
