I had the sensible idea of setting out the middle fruit bed centrally first, then to put the second bed between that & the front bed already built.

I'm still not entirely sure why, but no matter - a bit of rethinking on the hoof means that I will have four beds of 8' by 4' & a central 4' square bed, all with nice even 20" wide paths. Brilliant.
I pegged, levelled & fixed the second bed, & then roughly laid out the other three beds - all I need to finish these is some more wood for fixing stakes & I'm one length of 8' short too. To see it laid out is great though - very satisfying.

It was an enormous pile of bags & I was only going to do about half, but once you get into the swing of it you might as well carry on - it was dusk once I'd finished sweeping up & neatly packing the fifty-one empty bags away ready to be collected & refilled.
Reeking from wallowing in a skip full of manure, I headed home feeling virtuous - had to strip at the back door & head straight up to the bath!
