With a string and some color you can paint flowers or abstract pictures. Or you take the colors of the rainbow and throw it with the string on the canvas. Because I added some silicone oil to the colors, a few cells were created.
I've used wool as a string, unfortunately it lint a bit, but you only see it when you get very close to the picture. I noticed it only in the close-up. Here you should look for a lint-free alternative. Tiktus
