In the washing machine, yup -- unzip, stuff it in, add a SMALL amount of detergent, run on cold or warm, the machine won't be able to totally spin out the water (be close by in case it gets off-balance), then be prepared to RUN with a drippy thing to hang on the line. What's that, you say? Don't have a CLOTHESLINE?? Puhleez, girl. Go online and order a Retractable Clothesline like THIS ONE, there are several choices out there. One or two nails into the fence and screw in some sort of hook across the way, there ya go. Totally Martha.
