Peruse the classifieds in your local paper and you can usually find hay bales for sale.
You will need to arrange delivery and removal from your venue with a mate with a ute (ensure you get the venue's permission before rolling up with 20 bales of hay the day before your wedding). Some venues don't allow hay bales because it can leave hay everywhere, creating issues for the next-day's lunch service. Some venues don't allow them as they can be a fire hazard. So check first! It is perhaps more suitable to a private property.
When you think of it from their perspective, if their venue burns down because a guest is having a cigarette and it lights up a hay bale, or a tipsy guest bumps a candelabra into a curtain...that's all their weddings booked in for the next six months cancelled and a whole lotta disappointed brides!
There are three different types of hay bale around: big round ones, small rectangle ones, and large rectangle ones. You will most likely be after the large rectangle ones.
If you live in a rural area, consider hiring hay bales off a farmer rather than buying. It's actually pretty valuable stuff! And you know it's going back to a good home afterwards.
Old sheets, hessian, or lengths of tightly woven fabric make the best coverings and prevent hay puncturing your guests clothes. Soft loose weaves are not as effective.
