I have a quilt on my bed that's over 10 years old. It has many types of blocks so there's many pieces to it. I made it before I knew anything about thread and I am sure bought thread at Joann's. Because I have dogs, it gets washed and dried about 6 times per year. I used to use quilt soap bought at LQS but now I just use Tide. It still has all the stitching intact except for one appliqué that needs a little repair.
