I want a substantial scarf, but I also want it to be long enough to wrap around my neck a couple of times. So, I measure the yarns' wpi. The GreenBlueViolet came out a little bit thinner than the Arctic Ice, but I'm not worried about that. I settled on 24 stitches per row, on a size 6 needle.
With the Darker yarn end (Violet in this case), cast on 16 stitches.
Work a K1P1 rib for two rows ( *[K1, P1], repeat from * to end.)
DO NOT CUT YARN.
Attach most contrasty end of second yarn and work two rows K1P1 rib. (both my ends were the darkest teal, so I just picked one and started knitting.
*Start working with first color again, but pull it from UNDER the second color. Work 2 rows.
Pick up second yarn from under first yarn, making sure to pull it from UNDER the first. Work 2 rows.
REPEAT from * until almost out of yarn, end with 2 rows the darker yarn, cast off in rib.
The knittings is finished! I tucked the ends in, and this project is complete.
