We are getting ready to purchase a sewing machine so that we can finish our banners in house. Our question is, which process is better: lockstitch or chainstitch? What I have gathered so far: Lockstitch: Juki LH 3578 Pros: More durable, sews monofilament thread better and can sew in reverse. Cons: Folder is additional and it can be slower Chainstitch: Kansai DLR 1508P Pros: Faster, has additional needles, has a puller and allows room for rope to be sewn in. Cons: Not as good at monofilament thread, so we will have to stock many different color threads. It has the chance of coming unraveled. What am I wrong about or what am I leaving out. I want to get all my facts straight before we make a purchase. Somebody please drop some real world knowledge on me. Thanks!
