Had a coupla Good Wool
https://www.goodwool.com.au/ sheep skins since around 2008, one went with a bike I sold, the other was on the Russell Day Long pillion saddle, but it now sits between the child seat for the grandkids and the centre row in the Pajero. Use to get a bit grubby in the ST13, had a coupla washes, but nowhere as much as now, spilled drinks and food, probably eventually vomit and pee. It'll get a few scrubs over the next few years.
Had another one, a custom made bought secondhand from someone on the Forum, Gumtree, or similar. I think it went to STimpy or Cerebral Knievel or Duncan or Dougie (I think it changed hands at Wooli), one of them will be along soon to correct me (if need be) and provide a status report or update on the current owner.
