I cheated! I wore my Tuscany shawl to a party before it was done.
The punishment for this kind of thing is red eyes and a shiny face, even though I did all I could to avoid both.
How I did it: after the last row on the 8th pattern repeat I threaded a lifeline through all the stitches. I used "button sewing thread", it looks almost like machine sewing thread but it's much stronger. Then I bound off all the stitches using the knitted bind off, because that one is fast to do and easy to rip out.
Then I spritzed the shawl with water and let it rest for a while, before steam ironing it on the reverse side.
I loved wearing my Tuscany, but I'm glad it's going to be bigger still. The more lovely, soft, shiny, silky goodness there is the happier I am.
