Just a couple questions regarding some nets a mate made and had spare. He gave me some hemp nets that look fine and I'm happy with but he also gave me some other nets that are made out of what I think is knitting wool. Just wondering would these be ok for ferreting? I don't want to set them and a rabbit bolts, breaks it and I loose a rabbit. Just wondering what people who have much more of an idea than me think. Oh and on a couple nets instead of welded rings he has used key rings, what do think? Cheers in advance
