This one is a little keyhole scarflet, and it's probably just about a yard long. I don't have a definite giftee in mind, but I may give this or something like it to the teacher I've been observing, as I've really learned a lot by sitting in on her class, and she's been really generous with her time.
If you're curious, I used a version of brioche stitch called "patent knitting" which Laura described here. To make the keyhole, I knit the center stitches in garter stitch for a couple of rows, bound a few off then cast on the same number in the following row, knit a few more rows with those center stitches in garter stitch, then resumed normal programming over the whole thing. The only reason I changed the center stitches to garter was to keep the area around the keyhole more tidy -- if you're doing a keyhole scarf in a different stitch, this may not be necessary.
