I have my Nana's button tin still full of buttons. Numerous tomato pin cushions, thimbles, needle cards (one or two from Woolworth's at 19 cents for the entire card of needles!) and an ashtray from the Fountainbleu Hotel in Miami Beach. Long story short: I am adopted and my adopted folks lived in Miami for a while and ate at that hotel often. Fast forward to 2001 - I found my birth family and it turned out my birthdad was the chef at the Fountainbleu back when my folks used to eat there! Small world. I cherish all these treasures.
Other things: my Mom's Featherweight, my former GMIL's knitting needles, my Mom's crochet hooks and unfinished tattings, some fabric from the early 1960's that my uncle gave me (he was a pattern maker in the garment center in NYC). Probably more stuff but I can't think of anymore right now.
Great thread!
