- K2tog-tbl: Knit 2 stitches together through the back loops.
- K: Knit.
Step 1: K1, pass stitches back to your left-hand needle purlwise, k2tog-tbl.
Repeat step 1 until you’ve worked all your stitches. Pull yarn through the last stitch and weave in your end. With your tapestry needle, weave in all ends.
