As you can see, at this point I still had a lot of yarn left. I had a teeny little bit left over -- about the size of a silver dollar-- when I cast off the final stitch. If anyone is considering making this shawl with Sea Silk, one skein is exactly enough yarn for this project.

I have read that the Sea Silk looses up quite a bit during blocking, so I am curious to see what happens. I'll post pictures. Personally, I don't think a person can ever go wrong with silk, so hopefully Grandma will have silky shoulders for Christmas this year-- finally!
