But not what the OP was asking about.

But it's probably what he should have asked about.

I'd be concerned about damage to the bark of the trees. Anything that
slides over them will cut into the bark.

I'd probably use a bit of old mainsheet and a jammer, with cloth padding
under a bowline around each tree. But I doubt he'll have an old
mainsheet or a jammer. Ratchet blocks are cheap and easy.
