To finish the cowl, or to join any two ends of arm knitting together, use the mattress stitch. When you seam with a mattress stitch, it puts the seam on the backside or wrong side of the knit fabric and makes the front side look magically joined.
// Start the mattress stitch by placing the two ends of arm knitting abutted up against one another with the right sides or knit sides facing up. Your working yarn should come from the top. The ends should match in width. You may have to pull the cast on edge wider a bit to match up evenly. The stitches should give a little to allow this. Take care not to pull too far, though.
// Bring your working yarn underneath the first line of stitches on the right side (see the “v”?). Pull it all the way through.
// Bring the yarn over to the left side and bring the yarn under the first line of sitches on that side. Pull it all the way through.
// Repeat on the right.
// Repeat on the left. Continue until you’ve seamed the length of your work. Leave the stitches you’re making loose enough so that the yarn you’ve run through looks like a line of stitches itself.
Weaving in the ends:
// Flip the work over to the purl side to weave in the end of the working yarn on the wrong side of the piece.
// Weave the yarn under and over loops of the tighter side of the seam (the cast on edge).
// Tuck the yarn under multiple stitches in the seam and cut.
This cowl was made with Loops and Threads Cozy Wool.
