I have just bought a used Consew 327 R with twin needle, or single, feed (compound?) (There is a 327 R for sale on eBay.) I was hoping this would be good for sewing leather and lighter linings.The holes in the plate/feed dogs are quite small. I am still waiting for needles for the lighter materials but it sews the leather well. What are your thoughts or even better your experience of this type of machine?
