I am only posting this because it has been quite expensive for me. I live in town and have two very large pine trees in the front yard. The roots run the length of my house and cause sewer problems. I don't wash rag quilts the first 3 or 4 times in my washer because the plumber said the combination of tree roots and the huge amount of thread from the quilt cause problems for me. I don't know how many people have issues like mine, but I know I don't have the only trees. Something to consider when you look at washing these.
By the way, it is beautiful.
