Silk is surprisingly durable and long lasting. In fact, pound for pound, silk fiber is stronger than steel. All DonkeyGirl silk is washed twice: Once before sewing, and once during the dying process. This means you don’t have to worry about shrinking, or changes in texture.
Dry cleaning is always an option, but not at all necessary.
For best results at home, hand wash your garment in coldest water and tumble dry on high heat.
If you hate hand washing, you can also machine wash in cold water. The hand-dyed nature of the fabric can cause some bleeding, especially with raw sulk, so wash it by itself, or with like colored items.
Silk Velvet can be steamed to remove wrinkles, but can not be ironed. If you don't have a steamer, get your silk velvet garment wet, wring it out, then tumble dry with a towel on high heat. This will fluff up the nap and usually removes wrinkles. This trick works for the other silks as well.
Raw Silk and Silk Charmeuse can be steamed, or ironed on the reverse side.
Silk Organza is best ironed rather than steamed.
On a final note, you may be pleased to know that silk has one of the smallest ecological footprints of all the mass-produced textiles. Smaller even than organic cotton, as cotton is a water intensive crop.
