This common closet item will work as an inventive trellis. Additionally, as your plant grows and fills in, you'll hardly notice the wire hanger, so it won't even be an eyesore.
To support indoor plants, bend the wire hanger in half. You can straighten it from top to bottom to make things easier (including the curved neck) and then fold it in half.
To support vining plants, use your wire cutters to bend and shape your wire, creating a zigzag pattern. Stake it into your pot and wrap your plant around it for perfect support.
