Super easy to knit.

The striping yarn does all the work. ☺

Two different shapes to choose from - classic triangle or shallower longer triangle.

One solid main colour and one contrast colour - which can be self-striping or gradient yarn (another solid or semi-solid could also me used):

Allow at least 225m/250m of each yarn

Many thanks to the testers:
