I need to store a lot of charcoal and pastel drawings as I've recently gotten back into drawing.
I can't afford a proper solution such as a flat file at the moment.
I'm worried about stacking the drawings on top of each that can lead to possible damage on the drawings. I also don't want to leave them exposed to dust.
Is there a cheap solution that I can place between and on top of the drawings for the moment until I can afford a better solution?
