More recently I had an entry titled 'Sticky Sticky Erhu Strings' about using a piece of paper to protect your strings from the rosin powder on your bow.
The same reader decided to take a bigger piece of paper (A3 size) and fold it into half (instead of into a W) to cover both the strings as well as the fine adjustors. This way your strings are protected from the bow rosin and the bow hairs are protected from the fine adjustors.
Killing 2 birds with 1 stone.
Thank you Sam for your suggestion.
