My Mom received a new 1951 Centennial Singer Featherweight with all the accessories as a wedding gift from her aunt. She gave it to my sisters and I when she got a bigger machine. I was about seven. We used it to make doll clothes, rag dolls, aprons, etc. Then we got a white Featherweight in 1968; by that time we had moved up to making dresses (think Twiggy shift dresses!). On summer days back then, all three machines were often in use.
One of my nieces has the black 221now; the white one developed tension problems and lives in my sister's closet. I borrowed the black one last year while mine was in the shop. It still sews a perfect straight stitch, and the manual is still soaked in sewing machine oil!
