Pythagoras Triangle _ Knitted Shawl Pattern

This is a neck-down triangular shawl that should appeal to anyone who likes geometry and symmetry.

The vertical and horizontal stripes are created automatically by the increases. It is simple and quick to knit with very easy-to-remember pattern repeats and a delightfully simple, yet very effective construction!
