I use only DuPont dyes from France on a variety of textured silks. Once a piece is finished, it is professionally steamed for 3 hours which sets the dyes making them permanent.  Silk is a natural fiber accepting the dyes for beautiful vibrancy.​ 

Although I have sun tested my paintings for a week of direct California sun, I think it is wise to keep them out of direct sunlight.  Each piece will be framed according to museum standards. I use UV Plexiglas to aid in the protection of the piece.
