It's easy to use washi tapes. You can stick them onto wood, glass, plastic, ceramics, and even paper, as the tapes can easily conform to the crevices of your canvass with some flexibility and minimal creasing. What’s more, washi tapes can stick onto almost any surface without damaging the material underneath once you peel it off.
Since washi tapes are paper-based, you also won’t have any trouble trimming them down to your desired size. You can play around with precisely cut edges or the more rugged torn edges when using your washi tapes, too!
