From the page: The disposable cup deserves a second chance

DIY paint brush
Turning a plastic cup into a paint brush is an old trick from workshops and schools, where nothing was bought if you could improvise. It works because rigid plastic holds the handle's shape well, and bristles cut from another flexible material spread paint or glue with enough control for rough work.
What you need
- Rigid plastic cup (the party type or a large yogurt cup)
- Cleaning foam, a used kitchen sponge, or fabric strips
- Scissors
- Tape or a rubber band
- A skewer or an old pen (optional, for the handle)
How to make it
-
1
Cut the cup in half horizontally and keep the base, which will be the brush body — the firmer part grips better in your hand.
-
2
Cut a rectangle of foam slightly larger than the cup's opening; the foam is what holds and spreads the paint, so the denser it is, the more even the application.
-
3
Fit the foam into the opening, leaving half sticking out, and secure it with tape or a rubber band around the rim, tight enough that it won't come loose during use.
-
4
If you want a longer handle, poke a hole in the cup's bottom and insert the skewer or old pen, securing it with the same tape.
-
5
Test on a piece of cardboard before the final project, adjusting how much foam stays exposed.
Finishing touches
For bolder strokes, cut the foam tip at an angle, like an angled wall brush. After using it with water-based paint, wash with soap and let it dry so you can reuse it many times.
