(Video link here.)  Out of the vast collection of adhesive tapes that I keep on hand for various projects, my favorite is Japanese washi tape. It looks like paper, yet handles like masking tape, with an even finer ability to stick and release. Any wild design I want to make on a surface sticks like paint yet can be easily removed. 

The white blends in so well with my white walls, that I use it to disguise all sorts of flaws and scuffs. This 2-minute video by Japanese company Nitto shows just how delightfully morphable a room or design can be with the stuff.

Nitto is pushing the limits of washi-like tapes with Haru tapes. They come in eight different color families, different patterns (some traditional, some graphic, some transparent), different kinds of materials (some tougher for floor use!), and four different widths.

You can buy Haru tapes here. I buy less expensive, more traditional-textured MT Washi tapes at mt-tape.us,  Washi Wednesday, on Amazon, and at Etsy.
