There are many uses for plastic grocery bags in the workshop. You can use them to seal up brushes and rollers during a painting project, so you don’t have to wash so much stuff between coats. They make great miniature trash bags during cleanup, etc. The point is, it’s worth keeping a handful of plastic grocery bags on hand in the workshop, and here’s a great tip for storing them:
Stuff as many plastic grocery bags as possible into an empty paper towel roll. Then toss the roll in a drawer or cabinet. The cardboard tube keeps the bags contained, and it’s easy to pull one out at a time when you need it.
