Can anyone advise where I can buy heavy duty leather by the meter/yard at wholesale prices in CH?

Looking for 9 - 11 grain leather by the "sheet" so to speak, for making various motorcycle accessories.

Appreciate any advice.

I Googled 'Leder zu kaufen' (leather to buy) which wasn't super clever but seems to have done the trick.
There are a few Gerbereien here. (Tanneries). Gives you something to start your search with (and bumps the Thread which is always useful!)

Many thanks, i would have missed the Tanneries bit as my deutsch is mardinally less than rubbish.....
