I collect plastic lids from gallon jugs and use them for mixing paints. The plastic doesn’t absorb the paint, so they are perfect for small batches of custom color or creating different tones. I prefer the threadless lids, but others work, too. I have even started collecting them at work, and I keep a stack of them on my workbench. You can clean them out and reuse them or just dispose of them.
