Pudge

I inherited a vintage hand quilted crazy quilt made from taffeta, silk, corduroy and muslin fabrics from my husband's aunt. The quilt is 63 x 70 (seven inch blocks) and in sad, sad shape; just 16 blocks have not deteriorated beyond rescue. The quilt was given to me because I'm the only one in the family who regularly picks up a needle. Nobody in the family cares about the historic value of the quilt. Sigh. The only good news is that the deceased auntie took several pictures of the quilt before it deteriorated.

I want to turn the 16 salvageable blocks into a wall hanging, but I'm not sure how to do it so, please, send me some advice if you have any to offer. I hesitate to pick up my shears without some guidance on how to cut out the good blocks. Do they need to be stabilized and then sewn onto another fabric and made into larger blocks which I can assemble as usual?

Does anybody know if I will be wasting my time?
