I would throw them in the wash on warm gentle, small amt of soap. I would open the back seam. Then after they dry press them open. if you throw them in the wash I recommend a Lingerie bag to keep them from twisting and tangling. take out wet and air dry to cut down on wrinkles. You could even press them mostly dry I used the acetate/ nylon setting on my Iron. I used a wet pc. of cloth on my wedding silk. I made my wedding dress with 100% pure silk. beaded. I washed it and dried it then pressed it, no problem. If you are worried just wash one or two by hand. The least favorites to see what happens. This way you can be confident of tossing your finished product into a gentle cycle now and then. Wall hangings collect a lot of dust. :P :lol: :D
