Some time ago I a frogged a pair of old purple pot holders. They were at least 20 years old and therefore a bit faded and starting to fray. I can never throw anything away unless it's phychological baggage, but what to make from two balls of knackered cotton yarn? I knitted a few dish cloths as I already did some years ago with another set of pot holders. Some people make dish cloths from new yarn. That is something I can't bring myself to do. To me that's a waste, which is not to mean that people shouldn't make dish cloths from new yarn. I just can't.
They are no beauties, but I know they will be as great as the other ones.
