Don't let quiltncrazy's method throw you. I would gather your fabric, sort and wash like laundry, dry completely and protect it in something. I remember a while back someone mentioned not to completely seal fabric due to the chance of moisture/there could be mildew. I have decided to make sure fabric is dry and protect it. I have a lot of money and time spent agonizing over selections in my fabric. When I saw a little moth, I panicked and decided to wash/dry/ziploc one load at a time!
