For a very basic DIY portable basketball hoop that you can use indoors, all you need is a wire coat hanger. First, form the wire hanger into a circle. Next, bend the hook so it’s at a 90-degree angle with the hoop. Now you have a ring that you can hook onto anything in the house and use to practice your shooting skills with a soft, light ball. If you want to make your hoop a bit more substantial, you can cut a backboard out of cardboard and tape it to the hoop. You can also use string or yarn to add a net.
