I have these fabric buttons I call them in my big jars of mother of pearls buttons not knowing what else to do with them, They are handmade I do believe and beautiful. I bet they were the closure for a beautiful evening jacket worn over a beautiful tulle and satin evening gown back in the glamorous days of the 1930-1950's? Just day dreaming . Do you know anything about buttons like these? please tell Here is back of fabric buttons Is this one crochet?
