I am having my ceremony and reception at a horse ranch and the ceremony is outside. They don't offer any tables and chairs.
It looks like this-

I was researching rental places in my area and we can't afford to have chairs and tables inside AND other chairs outside for the ceremony.
I saw hay bales and fell in love with the idea. Being from Kansas I know of many places that can get me bales for cheaper than the chairs. (I know I need to have some chairs for the elderly or others)

Has anyone done this or went to a wedding where this was done? I plan on covering them with blankets/sheets something like in the picture so the guests don't get poked lol. I doubt I'll have the back part or the pillows, just the coverings. Good idea? Bad?
TIA
