Hello, I’m new to sewing and recently purchased a sailrite ultafeed LSZ-1 machine. Learning to sew has been a blast! I am working on some outdoor canvas projects. In sewing canvas I’m experiencing some ruffle type puckering in my seams that I would love to figure out how to eliminate and get a nice smooth seam. Please take a look at the photo attached and if anyone has any suggestions or ideas on how I can accomplish a factory professional looking seam I would greatly appreciate the help.
