Hi,
I got 12 out of the 15. The ones I missed where the ones about the history of machines and that weird looking thimble.
I have been quilting for more than 40 years. My mother bought a Featherweight in 1936. I didn't know when they were first invented. It was her most prized possession. At the time it cost $125. Since she was only making a dollar a day at the time it was a huge purchase.
