Really enjoyed this project. This was the first time using a sewing machine and I leaned a lot. figured I would start with a small pack for my son. Already know what to do differently on the next one. Here’s my problem. My singer 328k struggled to do the shoulder straps and some of the thicker stuff. Maybe I’m doing something wrong. Maybe I’m trying to get this machine to do more than it can. I’m looking at the singer 4432 heavy duty. Would you guys sway me towards a used juki or do you think this will do what I need. I want to be able to sew through multiple layers of webbing. I’d hate to get the 4432 and then upgrade down the line to something better. What would you guys recommend.
