Well, as DD explained it to me, you hammer some posts (sticks) into the ground in two rows about a foot apart, or whatever's required by your filler. The sticks are a similar distance apart in each row and staggered with the other row. You follow? Then you line up branches and other dead stuff in between them, just lying the stuff down to fill the space. Gradually you build up a screen. Gradually it all rots down naturally. So it's a kind of temporary fence made of stuff you would be rotting down or burning anyway.
You can also use two rows of wire fencing and stuff (verb) stuff (noun) (!) between them for the same effect.
My plan is to make a barrier to stop another pile of compost from tumbling down the hill (or getting kicked down by chickens).
There are pics if you google "compost fence".
Chest is back to usual niggle, thanks, but it wouldn't do to give in to it completely. I've done enough of that already. I just have to be prepared to collapse for a bit afterwards.
Asthma info that says it needn't stop you doing stuff is NOT TRUE!
