How to store pictures?
 

Good day, there are a large number of paintings and sketches.
Many unframed, without mount.
Tell me how to store, folding, etc.
at home.
Thank you

All that is on paper - Put clean sheets of paper or thin special " tissue " paper , if possible put in a plastic "files " or bags, and put in a folder. Access of light should not be. Now a lot is sold the right to hold papers or documents files of very different sizes and a variety of folders. Where everything for artists and office sections of large department stores.
Painting on canvas - on the contrary , requires coverage or it will darken ... It should be somehow fixed, otherwise it will break , and the foundation , and painting. It must be kept on the stretcher , or at least pinned to the cardboard ( hard , boxed ) , stored upright on a shelf where it is rarely staged in order to avoid scratching the side and passed to the light , preferably daylight .

How to store oil on cardboard?

The same way.
To be reached by light and not very cardboard "stir."

Darken, but will be restored in the light.
(Oil, from my own experience)

And the white paint and yellow in the dark.
Can be stored in the dark, but always before the show to hold in the light of day 10 ..
