A simple way to reuse or recycle some beat-up old garden fencing, or any other wire frame, is to turn it into a tower!
Step 1: Gather materials
I grabbed a bunch of different styles of the same general type of fence. They're all made of steel or iron, painted green, and have concentric geometries (little semi-circular loop inside the big one), which will be important later. The more sections of fencing you have the larger a structure you can build.
Also pictured are some work gloves and a set of pliers, which you may want if the fence sections are really dirty or in particularly bad shape. The pliers are handy for bending the wire.
