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.
CO – cast on
k – knit
WY – waste yarn
Rep from * – repeat from *
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.
How to work CO1-drop k1

How to work CO1-drop k2
