I like the reasoning behind washing a completed quilt. How do you wash the king size quilts? I hate to take any laundry to the places with big machines. You never know who used them last. We do have a laundry service just down the street from work. Do any of you have experience with this type of service? I have two very large king quilts that I would like to wash so they soften up, but don't know how to. Thanks have a great day!!!
