How to preserve water color/ Pastel color paintings?
I either frame my watercolor painting or keep them in a portfolio. For my pastels I frame them if I like them to protect them. My teacher said that the protective spray is not archival. Another thing to do for pastels is to build a box out of foam core. Only one can be stored in each box. The box keeps dust off your pastel and also makes sure that it is not damaged by something touching the surface. I do not do very many pastels because they are so hard to care for.
