Keeping paint brushes from hardening
If there’s something that all the artists who like to paint absolutely hate and can’t help but get annoyed over is paintbrushes getting rock-solid after they’ve been left unused overnight.
Painting requires one to invest an immense amount of time, so it usually takes more than a day to work on a project. In such scenarios, if you leave the paintbrush out overnight, the next day to ensure they aren’t as hard as Mjollnir (Thor’s hammer), wrap them in aluminum foil and place them in the refrigerator. You’ll surely be surprised at the results!
