Woohoo! We have a cattle panel trellis! I'm going to run out and take some pictures a little later.
We used four 5-foot t-posts and one 16-foot long cattle panel. The total cost was around $48, but this thing will last for y e a r s. I think it only took us about 25 minutes to get it up, which is a huge bonus! We (meaning my wonderful husband LOL) used a sledge hammer to drive in the t-posts and since the ground was wet from last night's rain it was a cinch. (Ok, he has big muscles. It might not be a cinch for a weakling like me to do.) I got the idea from the GardenWeb forums and I'm really excited that it turned out so well and was so easy to do. I can't wait to see tomatoes growing up it!
See it back there?
