rip 'em at the connections with an exacto or scalpel from hospital stores.
Then if you want it to attach, you can either pray or sew it on to a rock, works great - I've even had SOME luck using glue, but that's only if the base is a bit hardened with some dead skin, that way it doesn't slime up.
Otherwise like I said, pray - and at some point it MIGHT attach to something, maybe!
