Do you ever worry about getting stains on your dolls from the clothes they wear? Here's a tip that may help you.
When sewing for my dolls, I like to pre-wash cotton fabrics to remove any sizing (starch), and colours such as red, black and denim, are also treated to help their colour fastness. Then they are rinsed, air dryed indoors (stops the sun bleaching them) and pressed, prior to laying the patterns and cutting the garments out.
When purchasing garments, I find it's a good idea to check with suppliers to see if the garments purchased are colour fast. If new doll clothes were not pre-treated or should the supplier not know, I soak them in a tub/sink with a mixture of enough cold water to cover the garments, a 1/2 cup of white vinegar and 1/2 cup of salt for at least an hour. I DO NOT mix colours, and always do a seperate load for red and another for black or denim. Then I simply follow the steps above . . . rinse, dry, press.
