clearly nobody who shops at the Woolworths supermarket on Lonsdale street in Melbourne has any inkling of the wonderful things that can be done with onion shells...i found them on my last evening in Melbourne while foraging for a lime, sadly only after our classes there had finished.
and the worst of it was, i couldn't collect any - there are huge penalties for transporting plant materials from Victoria to South Australia.
so if any of my Melbourne dye-mates are reading...and need a source of onion shells...you know where to go.
