I'm finished! The shawl for my mother-in-law is ready to be dropped in the mailbox.
The shawl was knitted from yarn my mother-in-law already had on hand. Her mother gave it to her years ago -- the date on the yarn is 1977!
My mother-in-law has held on to the yarn, hoping to find a way to use it. She'd tried to crochet with it, and so did I, but the yarn was too difficult to pick up stitches. So I knitted it with circular needles instead.
I hope I can get this belated Christmas gift -- and a note -- in the mail tomorrow.
