So, here is the pattern... it has not been tested so if you find any mistakes please let me know!! I would love to see anything you make from this pattern!!!
4oz Worsted weight yarn
6 16” circular needle
8 16” circular needle
use whatever needle you need to get gauge. I get 5spi on 8's.
Cast on 103 stitches on smaller needle (a little loosely, remember, this needs to go over your head!), pm and join in the round. Work in seed stitch for 1.5 inches. Work last stitch of seed stitch pattern as k2tog or p2tog, keeping in the pattern, 102 stitches remain. Switch to larger needle.
Row 1: knit around
Row 2:sl5 keeping working yarn in front, k1. Repeat around
Row 3: knit around
Row 4: k2 *pick up float on right needle, lift up and knit the next stitch, allowing float to go behind worked stitch, k5. Repeat from * around to the last 3 stitches, k3.
Row 5: knit around
Row 6: k3, *sl5 keeping working yarn in front, k1. Repeat from * around to the last 3 stitches. sl3 keeping the working yarn in front.
Row 7: Sl2 keeping the working yarn in front, knit around.
Row 8: k5, *pick up float on right needle, lift up and knit the next stitch, allowing float to go behind worked stitch, k5. Repeat from * around.
Continue working rows 1-8 of the pattern until the piece measures 6 inches or longer if you prefer. Make sure you end of row 4 or 8 of the pattern.
Switch back to smaller needles. Kfb, then k1p1 around, end in k1, 103 stitches. Continue in seed stitch for 1.5 inches.
Bind off using a stretchy bind off. I prefer a sewn bind off. A great tutorial can be found here
Here's a wonderful tutorial for the lattice stitch:
Remember, this is only a cowl and feel free to play with the pattern! This would look great with a ribbed border edge instead of seed stitch, or you could even try garter stitch or just knit plain for a couple inches for a rolled edge.
