The cowl pictured below is 44 inches long. This is long enough to wrap twice around neck.
Here are the instructions:
Materials:
One ball of S Charles Luna lace weight mohair/silk/glitter yarn. You could also use Kid Silk Haze (no glitter). About 230 yards. Note: You can purchase either yarn at the Sow's Ear in Verona. About $14 per ball.
Needles: For the version in the photo I used size 7. For two previous cowls I used size 9. For the long cowl using fingering weight sock yarn I used Size 4.
Basically, use whatever lace-weight or fingering weight that you want. Use a needle size that is larger than the recommended needle size on the ball band.
1) garter stitch: i.e. knit every row
2) purse stitch: Worked on an even number of stitches
P1, *yo, P2 tog*, P1 Repeat between ** until the last stitch (which is the P1)
Instructions:
--Cast on 32 stitches. (Note, I used a provisional cast-on so that I could use the Kitchner Stitch to weave the two ends of the cowl together. If you use a traditional cast on, you will have to sew the two ends together.)
--Work four rows in garter stitch (i.e. knit every row) ; this gives you two rows of "garter bumps."
--{Work 12 rows of Purse Stitch. That is, P 1, *yo, P2tog*, Repeat between ** until one stitch remains in the row, P1.
Work 8 rows of Garter Stitch.}
--Repeat between { } until you have just enough yarn to work about six rows of garter stitch. I eyeballed this and used all but one yard of the yarn!! !!Do NOT work six rows of garter stitch!!
--Work FOUR rows of garter stitch.
--If you used a Provisional Cast-On, now you do the Kitchener Stitch to weave the two ends of the cowl together. If you used a traditional cast-on, now you do a traditional bind-off and sew the ends of the cowl together!!
Done!!
