This was one of my first colourwork charts. I designed it while holed up in a B and B after moving up North--wondering what to do next ;).

You read it from the bottom right corner moving left, then read the next (and all even rows) row from left to right, and the third (and all odd rows) right to left, etc. (Unless knitting in the round, like I was--then you read all the rows from right to left.)
