My 'Sail Away' installation did just that - one of the 3 sails moved around the dam a little bit as it was fixed to a floating log which obviously drifted around, so the corner became very dirty.
I tried to wash the dirt out and left the corner in strong bleach overnight - and guess what - the bleach has destroyed the fabric! Hmmmmmmm
Interesting effect but probably not usable in a practical sense.
Here are some of my favourite pieces from the exhibition:
'Renewal' by Fiona Dempster,
'Returning' by Fiona Dempster,
'Forest Letters' by Ken Munsie,
'Sounds of the Bell' by Kim Schoenberger,
'Windows to the Soul' by Kim Schoenberger,
'Droplets' by Barry Smith,
...and to finish off, a cheeky 'peek a boo' 'Sails in the Forest' from me.
