I purchased this quilt top in 2014 at an antique shop in Warrenton, MO. A lot of the embroidery was not completed, so I hand stitched that over a few days time. A few weeks ago, I took it out and looked it over. It had a lot of stains on it and was just dirty overall. So with some advice from the local quilt shop owner I purchased some quilt wash and soaked the top overnight. It took out all the dirt and most of the stains. I dried it in my dryer set to air dry - no heat. My main concern was that the edges of the appliques might ravel with washing, and they did just a little bit, but nothing too seriously. They had been machine stitched down close to the raw edges by the maker, then hand embroidered with a blanket stitch. That helped keep the edges from raveling to the point of no return. The quilting was kept pretty simple. Here is a short video of the quilting in the butterfly appliques.
