I 'inherited' a few quilt tops. I was able to get someone local who dated them and knew if they were of value. She also told me how to restore them. They do have a smell.
So right now I am in the process of turning over the raw edges and basting them. she advised me to purchase some RESTORATION online from [blue] www.softexpressions.com [/blue] to to help remove stains and such. Then to gently soak the tops in a gentle liquid detergent [no scent or bleach], rinse, and air dry.
Will see what happens.
There are some universities that have quilt collections and will assist you in naming any patterns. Unfortunately, I can't remember where I got my info, but think it was from Nebraska University. I sent pictures and they identified the patterns. In one case I could get a kit that was made to match the kit quilt I was asking about so I could complete it.
Have fun.
