My maternal grandmother recently passed away, and I inherited all of her sewing stuff ... several sewing machines, TONS of notions, fabric, etc. There was a box of quilting fabrics, quilt tops, and blocks that had belonged to her mother (my great-grandmother). She passed away in 1979, in her mid-70's, so her fabric was a minimum of 31 years old. She'd used newspaper to paper-piece some of the quilt blocks, and the date on the newspaper was in the 1950's. So that particular fabric has to be at least 55ish years old. :)
My grandmother had fixed some of her mother's quilt blocks, squaring them up and getting ready to sew them together. There are a bunch of 9 patch squares, and a bunch of double wedding ring pieces. Unfortunately she didn't get around to making quilts with them.
I hope to be able to do just that. :) Wouldn't that be cool ... quilts worked on by three generations? (I would say four, but my mom can't sew a lick! LOL!)
