Hi there from Australia. I cannot help you with locations, but I went to a tannery near where I live and dicovered they sell off-cuts at very cheap prices. Also, visit the local markets and second-hand stores, because there is a lot of items that get sold which are made of very good quality old leather. I have just finished making my own spooran out of recycled leather, and I am more than happy with it. Visit my thread in the D.I.Y section marked 'Judgement Day'.

Cheers,
Alwyn
