Sometimes I like to store my drawings where I can see them between sessions, because glancing at them in odd moments helps me to see them objectively. One time I made the mistake of leaving a drawing sitting out unprotected, in the middle of a dry summer, with all the windows in the house open. When I started to work on it a few days later, I was horrified to see that the whole thing was covered with a coating of
dust!
I spent the rest of that day lightly brushing and blowing the
dust away. Sadly, I spent my next free day re-drawing some very dark details that had been lost in the
cleaning process.
My very simple solution for
dust, and other mysterious spots and specks, is to tape a piece of
plastic food wrap to the back of the drawing board. After a while, the wrap loses most of its clinginess and you can easily flip it from one side to the other.
