When painting, I always have a stack of cut-up t-shirts next to my water jug. These are the best material I've used to clean my brushes and wipe paint off (or around on) the canvas. Absorbent, durable, reusable - and there's always a worn-out t-shirt around if I need more.
When they get full, I run them through the laundry to soften them back up. But after a certain point, they just won't absorb any more.
Would you throw these out? I certainly can't. They go into the collage material bin.
