See the video tutorial here. Double Trellis Stitch

There is no yarns or gauge listed because it can be used with any yarn in any gauge. Just be sure to use the appropriate hook size for the yarn you are using.

This lace stitch can be used in any number of projects from shawls & afghans to shopping bags and table scarves.

It is especially lovely in a self striping yarn or thread.
