When my MIL passed away in 1997, I found her stash...lots of crazy quilted cotten fabrics on squares from fabrics that she had been making clothes for the family for YEARS!!!!! Don't even know how far back some of them go. I also have 5 or 6 yardage of seer sucker...don't know how old, but must go back several years before she passed on. She had not been able to see for 10 or more years, so that would put it easily back in the 70's or before!!!!
