Recently, while doing the laundry, I decided to "retire" some of Tom's old socks that were about worn out.
I did't throw these away, though. Instead, I used some scissors to cut them up and make cleaning rags.
First, cut off the toe.
Next, cut along the folded part of the sock, all the way up the back.
You end up with a nice size cleaning rag that is soft and absorbent. They can be washed and reused if the cleaning job is light. However, for messy jobs, such as refinishing furniture, you just use them and throw them away. Easy cleanup!
