How do you store your quilts and blankets long-term so they are not damaged by age?

you could try lining your chest with acid-free paper. If you are storing fabrics long term, I would definately check on the fabric at least twice a year.

Before putting it in the box make sure that it is clean, completely dry, and that you are keeping the box in a clean, cool, dry environment away from mice.

I’m going to take them out and wash them tomorrow.

I have many antique quilts and I either fold them on a very large wooden quilt rack (I refold frequently so that there is no permanent crease) or hang them on walls that do not get direct sunlight.

I do keep woolen blankets in a cedar chest during the warm months.

Milo has solved the mouse problem around here so that is no longer an issue.

My mother-in-law wrapped her quilts in blue cotton cloth and secured the cloth with safety pins. I don’t know why it had to be blue, but I’ve left them as she wished. Unfortunately, she died some 25 years ago, bless her soul.

I lay a sheet on top and fold it up so the sheet is on the outside.
