Now that the holidays are over, I can post things made as gifts. Catty is inspecting the diagonally-striped scarf I knitted for my friend Carrie. To make it, use two colors of super-bulky yarn, such as Rowan Big Wool, and 15mm needles.
Cast on 14 stitches.
Row 1: Knit across with color A.
Row 2: Increase 1 on first stitch by purling into back and front of stitch. Purl across, but P2tog on last two stitches.
Repeat with color B. Don't join the yarn throughout, just keep picking up the different colors as you alternate. Continue alternating colors every two rows until you reach desired length, bind off.
