What to do with your old t-shirts...

In the 90's and 00's I used to buy heaps of Tin Tin t-shirts when we visited Bangkok. They were well made and 100% cotton. Often a conversation starter with flight crew.
These tees were well loved and well used. A few years ago my wife labelled them with a permanent marker "HUO" (Home use only) as they were getting threadbare and frayed around collars and cuffs. But I persisted in wearing them as they were big and comfy.
Last year she (who must be obeyed) made them into cushion covers for our spare room. It's a compromise I can live with.
