Question about "old" crazy quilts or pillows
 

I think many of them were made of velvets, silks, "fancy" fabrics -

I don't think they were washed before cutting "way back when" -

My question is: Were these made to be "used" or "just to look at" in the parlor?

They don't look washable - and I am wondering how well the fabrics would survive dry cleaning?

How would one clean one of these items?

I', no expert but my Grandmother made one. She laid it out over her piano in the parlor and beat it with a broom when it needed dusting. I agree, I think they are too fragile to wash.

They reached their popularity in late 1800's. They were NOT meant to be washed. Meant to be laid over the back of something in the parlour. That is why many are smaller than a normal size. Also meant to display a woman's needle work skills with the embroidery. Do not, not not dry clean it!! Check out this link from the Smithsonianason.

I would never do that to a cotton quilt, let alone more delicate fabric
Best (general) way to clean it is with a vacuum and pantyhose over the end, to protect the quilt while you vacuum up dirt.l This link should tell you what you need to know.
