I wish I would have done all of this research before I bought tape and stuck electrical tape all over my walls. I love the thicker 3 inch electrical tape. You can buy the 3 inch wide black electrical tape on amazon here. The 2 lessons I learned are do your research and think outside the box. Electrical tape, floral tape, washi tape, and masking tape can work wonders in a rental or to decorate a hula hoop! Have you ever used electrical tape for things other than taping wires?
