Skills: knit, purl, sl1
Finished Measurements: dependent on yarn
Gauge: not important, instructions are written for almost any yarn
Yarn: approx. 200g of anything from sport weight to bulky weight
Note: sorry to be vague, but amount and yardage is dependent on the weight of yarn you choose - ask at your local yarn shop
Suggested Brand: your choice; I used a bulky weight wool for the example on this page or 4 balls of Noro Kureyon works well (seen on pg. 2)
Needles/Hooks: match to your yarn according to the label
Other Materials: tapestry needle or teeny crochet hook
CO 24 sts, or an even number.
Row 1 (RS): *K1, bring yarn forward, sl1 as is to purl*, rep from * to * to last two sts, K2.
Row 2 (WS): *P1, with yarn in back sl1 as if to purl*, rep from * to * to last 2 sts, P2.
Repeat these 2 rows until scarf reaches desired length. BO and weave in ends.
My advice for substituting yarn in a pattern is almost always the same: knit a gauge swatch that is at least 20 sts x 15 rows (depending on your yarn). The bigger your swatch is, the more accurate your measurements are going to be. Knit the swatch in the pattern stitch to be used.
Get a fine point knitting needle and count out how many sts you have in 2 or 4 inches (again, the bigger sample you are taking, the more accurate). I try to avoid counting the few sts at the edge of your fabric for accuracy. Also, you can't cheat and only knit a few rows - you need to knit more than that to be accurate.
Now you just need to know how wide you would like your scarf to be. For example, did you count 20 sts = 4 inches? For a six inch scarf you would need 30 sts.
