Round bale blinds, straw bale blinds, hay bale blindsYou can cover a hay bale blind in all types of covering. Straw works really well, so we should call it a round bale blind with straw. Or a hay bale blind looks great with alfalfa vegetation.I use some old bahia from a small round bale I was feeding my goats and the thing fooled all my neighbors. Even the guys who hunt. They just thought I wasn't buying the small round haybales anymore, but I was buying the big round bales.
