This is worked in a 2x2 rib for four rows, then two rows of garter stitch.
Knit first stitch, K2, P2 to last stitch, Knit last stitch. Repeat this row 4 times.
Knit all stitches across. Repeat this row 2 times.
Continue until desired length.
One skein gives approximately 14.5 inches. I'm on skein #4, and I suspect I'll have to go to skein #5 to finish the scarf to the length I desire. It's a lovely yarn, easy to work with. There is a bit of variation in the thickness, with some sections being quite loose and fluffy while others are tightly wound. I love it. The colors are so vibrant! I went back to the store the week after I bought this to get some more, which I plan to make into a hat.
