Years ago – maybe 17 or so – I had the same great grandmother’s embroidery sampler cleaned, restored and reframed by a textile conservator in my area. The cost for all that was around $1,500, IIRC, and the crazy quilts need a lot more work and are much larger in area. As mentioned in the first link Deborah T posted above, the patches are made out of silk, and many of them have shredded. Ideally, I’d want the quilts cleaned, repaired and mounted in sunlight-proof acrylic or glass shadow boxes. Can you say “lots of money”??
Since I have two of them, I could do them both and then leave one to each son.
I’ve been afraid to find out the cost, however.
