For newbie like me, we don't need fast and too much power on our sewing machine. We just need something that easy to operate without dashboard like a pilot board in the airplane.
Yes, that simple stuff can make me learn faster and quick adapt with new environment that we never seen before. We need needles with bigger hole to add our thread in and use it to knit straight line in our fabric.
I found one website that explain all of this in simple way, you also can check them here. They are simplify every complex thing. And tell us what is this and that with engrish.
Once again, you can check http://adelsewing.biz/ to learn that things.
