Yarn: Blue Moon Fiber Arts "Periwinkle" (that's the yarn name, not the color), 1 skein in Marbles colorway
Needles: US size 13, long circular
Gauge: About 2 stitches per inch, but not incredibly important
Cast on 177 stitches, leaving a 8"+ tail at the beginning. If you or the recipient are 5'4" or shorter, you might want to cast on 155 or so instead. I'm 5'2" and even with my Janeway boots on the fringe drags on the ground.
Instead of turning and knitting back the way you came, you will work this scarf from the same end for every row - the end where you started casting on. So go back to that end, and mark the right side with a safety pin or locking stitch marker.
You're going to force the yarn to pool, so search for the place in the color pattern of the yarn that matches the colors on the needle right where you put the marker. This is your Color Starting Point.
You're going to leave a long tail at the beginning and end of each row for fringe, so make sure you have 8 or more inches before the Color Starting Point. If you do not, then search forward in the yarn for the next Color Starting Point.
Row 1: Attach at the Color Starting Point and knit to end.
At the end of the row (and at the end of every row) search forward in the yarn for the next Color Starting Point. Break or cut the yarn exactly halfway between the end of the current row and the Starting Point for the next row.
Row 2: Go back to the beginning and attach yarn at the correct point, and purl to end. Finish row, as in row 1.
Repeat these 2 rows - slightly varying your Color Starting Point by a few stitches to make the pooling a bit uneven - until you are almost out of yarn.
Bind off loosely, so this edge doesn't pull tight or curl in.
Finish the fringe: Take the first two pieces of fringe and tie two knots to secure the edge of the scarf. Then take one of those 2 pieces and the next free piece and knot. Repeat until all fringe is knotted on both ends of scarf. Trim the fringe to about 8-10" per piece, trimming each piece to a thin part of the yarn and keeping the pieces uneven in length.
To give as a gift: Roll like a giant cinnamon bun and secure with a big bow and tag.
