VH-I have an embroidery sampler from my mother’s side of the family. It was done in 1826 and seems to be in pretty good condition. I don’t know when it was last cleaned, but it has been at least 50 years and I have no idea when it was framed. I just love it and have been very careful to hang it in an interior hallway that gets no sunlight. Would there be any benefit in having it cleaned/restored or do you think I am better off to leave well enough alone?
