I love it! I haven’t had a sewing machine in years. I gave my old machine to my son so he could enhance his cosplay costumes. Fast firward five years later and I gift myself the Singer Heavy Duty 6600C. I’m quickly tailoring new purchases to fit like a glove instead of farming out to expensive tailors. I’m thrilled about new projects that are sure to come as a result of my lean mean sewing machine. By the way, it is surprisingly lightweight and easy to set up. Love, love, love it!
