Removing the cardboard tube leaves you with a not very useful partial hanger.
Here is a quick and easy way to convert this into a hanger for lightweight items such as camisoles. My camisoles need hangers with notches for straps and those are harder to find and more expensive than just plain plastic hangers.
Step 1: Gather
Pliers with built-in wire cutters
Step 2: Cut
Use wire cutters to cut off the bent ends of the hanger.
Step 3: Coil Ends
My ends were not rough and they coiled neatly inward but if you think the rough ends could snag your clothing then maybe a little dot of "shoe goo" on each end before coiling. But that will add at least 24 hours to the project to let the goo dry completely.
