Garter Tab Cast-On for Triangular Shawls

The Garter Tab Cast-On is an ingenious way to invisibly start a triangular shawl.

A provisional cast-on is used to cast on two or three stitches, then the working yarn is used to knit in garter stitch until you have a little strip of fabric - the "garter tab."

Picking up stitches along the edge of the tab and in the provisional cast-on places the stitches in such a way that you are ready to start the triangular shawl and it is impossible to tell where you started.
