Merry, merry.
Now I know this is probably too late for you to knit up for Christmas unless you are a super fast knitter, but I sort of cobbled together a quick scarf pattern based with great affection on the Elizabeth Zimmerman February baby sweater from the Knitter's Almanac that I am knitting for my sister and thought I would share...

Here you go:
Gull ScarfCast on 27 stitches with a long tail cast on. Knit three ridges of garter stitch. (This will be about 6 knit rows).
Begin the gull pattern, beginning and ending with three knit stitches:
Row 1: Knit 3, Purl 21, Knit 3.
Row 2: Knit 3, *K1, K2TOG, YO, K1, YO, SSK, K1 (Repeat from *two more times), Knit 3
Row 3: Knit 3, Purl 21, Knit 3.
Row 4: Knit 3, *K2TOG, YO, K3, YO, SSK (Repeat from *two more times), Knit 3
Repeat until the scarf is about as long as you want it to be.
When you get to nearly the end of the yarn (or as long as you feel like making this), you will end with three ridges of garter stitch. (This will be about 6 knit rows). Cast off in purl.
Pattern notes: This is 7 stitches long over 4 rows, so you can add repeats of the gull pattern if you want a wider scarf- it just needs to be multiples of 7 plus an additional 6 stitches for the garter edges.
I am still knitting on my scarf, which I have done in
Rowan Cashsoft DK yarn in the "Madame" colorway, which is a really pretty bright pink. I am planning on knitting this with two skeins of the Cashsoft, which is about 240 yards of DK weight yarn. I am using a US size 8 needle, but you could go up a size or down a size without impacting the size of the scarf too much. Gauge doesn't matter too much, since it's a scarf. I would say that if you are a really tight knitter using a larger needle would be good, but use your own judgement. You may even want to knit a few rows of the gull pattern as a test to see what you think about it, first.
In any case, happy knitting and a happy holiday- whatever you choose to celebrate.
