My flannel bed sheets from college had a lot of sentimental value, but they were full of holes. As kitchen rags, I get to enjoy their color, texture, and the memories they remind me of more frequently than if I had stuffed them in a save box.
Favorite worn-out jersey knit t-shirts are cut up and stuffed into an old tissue box that I keep by my bed. Corporate logos clutter my mind, so I like to cover them with small drawings or pretty textures snipped from magazines.
A box of rags made from old clothes is great to have in the kitchen or garage for spills, straining, and messes that might ruin your nicer towels. I spend less on paper towels.
Wash your rags along with your regular laundry. If they get too soiled, they’re easy to toss. For easy cutting, buy a pair of scissors that you use exclusively for fabric and label them as such.
