I currently own a 222K Featherweight (free-arm model), one 221 Featherweight that will be sold in a while, a black longbed Singer 301 that is new to me, but will be used a lot, a tan Singer 301 in a cabinet that is currently for sale, a Janome 3010 QDC for travelling, a Janome 11000 for sewing and embroidery, a Janome 1600P that is on my Grace Pinnacle frame for quilting. Just inherited a Singer 115 treadle in a parlour cabinet, and restored a White VSII treadle that I'm thinking of selling. I like old machines and get a kick out of buying them and fixing them. I will keep the 222K Featherweight and the black 301 and I do have another 222K coming my way as soon as the postal strike in Canada stops.
It's a lot of machines, and I do own a serger and a Janome MB4 for embroidery. I am finished buying now and am making some choices as to what to keep and what to sell.
I don't intend to keep machines to pass down to family, as we have boys and they don't care one iota about my stuff. I will just use them, enjoy them and then sell them when I no longer need them.
