CO1-drop k1 is the abbreviation used when a pattern wants you to cast on one stitch, then drop the following stitch. CO1-drop k2 is the abbreviation used when a knitting pattern wants you to cast on one stitch, then drop the following two stitches.
This stitch is most often worked when working a drop stitch pattern. The cast on part of the stitch is used to balance out your stitch count, since dropping stitch(es) removes them.
Note for Cobweb and Cuff Pattern
Before working round. Use a tapestry needle and WY to thread WY through each k1 following a purl stitch (skip second knit stitch where there are two together) on needles and tie ends of WY together.
