I saw a photo somewhere that used these, only thing is they were completely covered with vines and could not tell if they were made out of wire/mesh or what. Does anyone know where to get them or has anyone used them for arbors. I understand they are quite long and wide to where they can be folded over like a tunnel. Will be going to the feedstore in the next town over to see if they have some there. Sounds like a great idea to me. Anyone having any input or advice regarding this subject is greatly appreciated.
