Crochet hexagons

I've been crocheting these hexagons from a pattern I found on the web. The original was for a blanket, but I wanted something smaller and I thought it would make a cheerful cushion cover.

Hexagons are well known for being a tessellate shape. Bees use them and they're a traditional shape for patchwork quilts. Unfortunately, you end up with a zig-zag edge. No problem if you're making a shawl or blanket, but it's not going to work for a square cushion.

So my next job is to design a half-hexagon to match and also work out how to fill in the little triangles!
