Circles or Rectangles?

I pose it as a question, but I’ve actually decided I’m going to dig up the beds I’ve already constructed and lay out a seven circle mandala a la Linda Woodrow. Mine’s going to be rather smaller than her plans though (the circles will be 1.2 m in diameter rather than 4) and there will be no chook dome (yet…).

This link will give you a better idea of what it might look like. Mine won’t look anywhere this neat though, that’s guaranteed! I’m not intending to raze my garden and lay it out all at once. I’ve a more haphazard approach in mind.
