When one is totally involved in the hobby of Machine Knitting, we tend to acquire more than one knitting machine. We seem to want one of each gauge, but tools tend to get mixed together.
Today, I have been spring cleaning and labeling my tools with nail polish. It dries nice and hard. We live in a “bonus” era. Nail polish colours are every colour of the rainbow and not just various shades of red.
CAUTION: the nailpolish dries VERY FAST; Hard to remove mistakes.
