Progress on Swallowtail Shawl

Over the weekend, I've worked through the third and fourth chart of the pattern. All that's left is the 10 rows of the fifth chart...not that 10 rows isn't enough. It takes me over to 20 minutes to work a row (what with counting and knitting the stitches). I'm hoping that if I work on it during the evening, I'll have the shawl completed by the weekend. I don't have blocking wires and will have to consider investing in them for this project. I'm not sure I want to block eyelets with pins.
