Can wall stickers be stuck on woodchip?

Or will they just peel off?

Would love to get some for DS' room but don't want to waste money as they are quite pricey.

No they will not stick properly and will be bumpy.

Can you stick them to something flat and hang them instead?

Ah okay, that's what I thought.

Hmm, maybe, the hanging idea is good. Although might just go with the home made route instead, get him to help make some stuff on giant paper and just blu-tac it.
