i'd try calling up agrisupply. not sure if there's one out your way, but there's one in garner. also try southern states.

for beans i often will construct a trellis of 3 bamboo poles teepee style, which you could put probably 6 plants around. if you watch for abandoned homesites with boo and then look up the tax records and contact the owner you can probably get permission to harvest some. then you just run twine in a spiral up the boo and the beans grab onto it.

also, there is a nylon netting product sold that has about 4-6" holes in it and is very durable. i have it on 2 permanent trellises and it's been going for several years. i got mine through pinetree gardens, but i think i've seen it at logan's. you'd have to fasten it to something, but it's much easier on the hands than wire. you can build with the boo and attach it to that or to anything, really. only downside is it tangles easily when you're installing or taking it down. it gets mildewed after a season, so it isn't glaring white after a bit (a good thing).

I see them at the Tractor Supply chain of ag-supply stores.

Ditto on Tractor Supply. We're in the process of getting the feed lot panels to fence in our back yard (the front will be picket fence, with picket gates where it joins the wire panels). They're about $15 for a 16 ft x 5 ft panel. They don't deliver however, so you'll have to figure out a way to get it home. My hubby added long support boards to our small box trailer to get them home. Do a search for Tractor Supply and you should be able to find the nearest location to you on their website.

Thank you all for your response.

i really like bamboo tee pee idea. i saw some in dollar store. Do they usually cost 1 for a $ ?

I see lots of abandoned home on my way. lots of new construction sites. They throw so much of wood and paint buckets etc.. i think they are going to construction debris site. Once I picked two wood pieces but was really shy about my neighbors watching me. I never went again. :-)

We are using lengths of 4' high stock fence. It naturally "curls" from having been rolled. We take a piece of it long enough to make a circle about 24 inches in diameter and wire the ends together. It's heavy enough to stand in our sandy soil without pegging the bottom but that would be easy enough to do if your ground is harder. The rolls of stock fence can be found at Tractor Supply or the big box stores. Probably good hardware stores, too. And they can't be as expensive as ready made panels.

"I checked in home depot and lowes. They only cary wire fencing with 2"x4" opening. I want the opening to be atleast 4"x4" or 6"x6"."

Lowe's does have wire fencing with 6x6 opening.
I need some to make the top of my grape arbor.
I have not bought any yet because it cost a lot.
It was $107 for 330 foot roll.
