Home Depot sells some CRW in sheets that is 42" W and 84"L. so you can make a 20" x 20" by 42" tall square cage out of it (OR 26" in diameter, round) . It costs $7.20 here.. They also sell 48" wide in big rolls.. It costs about $100.

The Home Depot here sells 5 ft x 100 ft rolls for $97 plus tax. I bought a roll a few days ago. My cages are 24 inches across by 5 feet tall.

The pic is of two I made yesterday in a 4 square foot bed. I made 10 so far, and there is still plenty left in the roll.

The beat investment I ever made was in Texas tomato cages.

Can you post a picture of them jennie?

Lowe's here beats the HD price on 3.5 by 7' panels by two dollars, and the heavier roll mesh at HD and Lowe's here is 150' long for the same price. Maybe it's a regional variation, It also makes a wicked pea/cuke/bean trellis.

Rereading the post, the OP was requesting how to build a specific cage. Not suggestions on cages. ZZachary, many pictures of Texas tomato cages on the Internet.

Sorry! I read it wrong and my name is not Zzachary. It's Zackey.

Sorry Zackey, I'm not reading things well today! It was me who didn't read the original post enough to know he did not want suggestions of cages but instructions on how to build. Do look up Texas tomato cages though. I have had mine I think close to 10 years.
