I was taught NEVER to use Woolite or any other detergent due to it may damage the coloring in the fabrics. Only use Orvus which can be bought at farm stores or use a liquid especially made for quilts. Do not use fabric softner. Dry flat inside or outside like your grandmother did but be sure to cover it up with sheet to keep clean. It will dry well on bushes also. May go in dryer on fluff to fluff up batting. Good luck.
