I'm putting some killer, rare pieces into the shop tonight and a good portion of this week's focal pieces are some 1940's stunners. These pieces are getting harder and harder to find, as rayon is a delicate fabric prone to fading, stains, and becoming brittle.
Sometimes I panic when I think about how 40's pieces are disappearing so rapidly; even ten years ago they could still be dug up at estate sales and the occasional thrift shop. When I do find 40's pieces, more often than not they need repairs, soaking, or rebeading. It's always such a risk working on these fabrics as you just never know how they will respond; I would say that I lose about 1 in 5 pieces trying to bring them back to life.
Soaking them will either yield beautiful results and leave you with a bright, stain-free beauty or shrunken, dye-bled, shredding mess. Spot treatment sometimes works, but usually it just makes a big fat hole in the fabric or leaves unsightly water rings. I hold my breath every time I take a 40's rayon piece out of a soaking bath, because you just never know how it's going to look.
