Hi, I spoke to MIchelle from sustainable hemp products on line and she was really helpful, they have different types of wool covers which are already lanolised, there are care instructions on the website as well. I came across these when I googled bamboo velour nappies, they sell 'lushies' which look so nice! I would have been tempted to buy some on line but she says she does most markets so I will see the real thing at a market on the coast in May and will wait to then.
