We just have standard round curtain rods over the windows
. I think they're called cafe rods. They are between a quarter and a half inch in diameter. Threaded the rod through the folded-over sleeve at the top of each curtain and there you are. Planning on using something similar to twist ties to fasten the rods to the holders, though. They tend to fall
out of the holders if we hit a lot of bumps on the road.
Sorry for the delayed response. I haven't checked in to the forum in way too long.
