Tea strainers. These don't look very practical. It's easier to use tea bags.

I got talking to the lady who collected the tea strainers, and asked her if there were any historic curiosities in the village worth seeing. She asked someone to mind her stall for half an hour and led the way next door to the church, where in the porch she showed me a medieval outline of a foot, marked in the stone, used as a measurement guide by the local cobbler. On the outside of the porch she showed me a sundial which was used in the pre-Reformation period to indicate the time of the next Mass. Then she launched into an explanation of how the clock in the tower worked, and showed me the weights (hanging down inside the church - they could kill someone if they ever fell). She was very chatty, aged about sixty, interested in everything and everyone. I mentioned that the Women's Institute had a formidable reputation locally (enforcing social control) but she told me they were nothing compared to the Mothers Union.
