Well it sewed through the first seam fine with no problem. I was using a roller foot and a jeans needle. I think it's just inexperience with the fabric and operator error because my machine sews through 8 layers of jeans with ease so 2 layer of vinyl covered cotton should have been a breeze maybe my stitch length was too short because it started to sew than just jammed out of nowhere and the cutter would not function after that
