Bzzt. Lose 8 bodgepoints for using materials incompatible with farming
tradition. The *only* structural techniques acceptable for lashing up
*anything* in a haybarn are (a) baler twine - for which strimmer line
is not really an acceptable substitute - and (b) gert big blobs of welding.
I thought we'd established this as an unalterable rule of nature a few
years ago...

Surely it would be possible to bend the rules a bit and thatch the roof
internally (using baling twine to hold it in place of course)
