I have a quilt the top was made in 1933 and quilted in late 50s or early 60s. I just wash it on regular and dry on regular. The binding needs replaced but otherwise it is in good shape. It was given to me in early 60s and at that time, I knew nothing of value other than it was old and it we used a lot. Up until that time it was rarely used, if at all. At the time I believe I even washed it in a wringer washer. I was young, knew not much . Even had to line dry it at the time.
