Every serious sewing session includes a tea break. Five minutes in the kitchen for a breather, dreaming up marvellous projects and scoffing biscuits, back to the sewing machine with the second mug of tea, put it on the table, start stitching again from where you left off... aagh... oh horrors...
The moral of this story applies mainly to right handers using a hand machine.
Don't put your tea on the table too close to the sewing machine. As soon as you start sewing again the tea goes flying.
How do I know? Bitter experience, many years ago when I was young and foolish. Such an awful waste of tea. I just want to spare you all the same agony.
