Some ideas for your party that we've used at R&R before. For extra seating you can use hay bales and place some burlap just over the tops. We did this at Sagamore Farms for an UnderArmor party and it worked out great. Just use some cheap twine to tie around the base and you're done. We have tons of burlap already cut if you like this idea.

Here the matterial is just tucked under

the bale twine. Burlap on the bottom

to match the pillows or a brighter or even darker

fabric would punch this group up a bit.

I have a lot of smaller pillows lying around

and they're easy, easy to cover.
