My mother has a Singer 160 sewing machine. She uses it pretty often and has never had a problem. It’s versatile and can be used with different types of fabrics. And it surely stands out with its appearance. Black and gold polish makes it classy and simple.
I just remember myself doing the same stuff a couple of years ago. But then, I got my Tippman Boss machine and started doing everything a way faster than when I did it by hand.
If you're looking for a heavy duty sewing machine then pay your attention to Tippmann Boss model. It can sew through the leather of up to 3/4″ thickness. But, this machine is somewhat expensive. Today it costs $ 1,350 on Amazon.
