People throw away electric fans all the time. I rescued these two fan housing halves from my neighbor's trash.
You can make single baskets that hang with wire from an overhead hook, or you can hang multiple baskets in series, like this double basket design.
Step 1: Materials
The wires are attached to the hook, and the four free ends dangle down to hold the baskets.
I bend the rebar either with pliers, or with a 2-pin bending jig.
Step 2: Attaching the hook
I then got the eye end of the twisted wire worked into the rebar hook and twisted it a few times around the hook. This secures the hook so that you can hold the basket from underneath while placing the hook higher than you could normally reach.
Step 3: Hanging the baskets from the hook
If the lengths of your wires from hook to the top basket are the same, the basket will hang level. If the wires between baskets are the same, the baskets will be parallel.
