I am sewing for more than 31 years and I am a crazy sewing machine fan. 

I worked with manual sewing machine, treadle machine, automatic zig zag white plastic machine, umbrella sewing machine, serger and a lot many sewing machines.

Hence, I seprate the usefulness from the fancy decorations and tell you the truth, if a sewing machine really fits your needs.
