I've made all my quilts on 'vintage' machines...
I was using a 301 - love that machine, but switched to the 319 because I wanted something that had some fancier stitches and I don't have to drag out another machine...
If any machines are 'gathering dust' it's the Brother 2003D and Singer XL1000 - both embroidery/sewing machines
I keep threatening to dig them out of the piles of 'stuff' but so far it hasn't happened..
