I use three different sewing machines for making clothing. They are: a serger, a coverstitch, and a regular sewing machine. They're all home-sewing machines, so they definitely have their limitations, but they do a fine job for now, until I have the space to upgrade to industrial machines.
I also have a blind hemmer that needs some adjustments before I can sew with it. That would make some of my alterations work a total breeze.
On my wish list: all industrial machines! They're fast and powerful. The drawbacks of using home machines are that they're kinda slow, and they have difficulty sewing through many layers of fabric. Not so with an industrial. Drawbacks of industrial machines are: size, noise, and price. The noise wouldn't really bother me, but we have no space for them in our apartment right now.
Another thing on my wish list is some sort of way to apply bindings to the necklines of knit clothing. I can do it with my regular machine, but it's slow, and hard to get it perfect. I'd like a solution that can fold it and sew it in one movement. I know such a thing is out there, I just don't know what it is! If anyone has any ideas or other sewing machine recommendations, let me know in the comments. Tell me about your sewing set-up!
