Luckily Singer is a larger company with a larger following so info on their machines are typically found somewhere with a little digging if needed. I’d safely assume your not going over 92 thread on it and other than that just check out resources for needle to thread and needle to material types and information. Dial in your stitch quality while changing fabrics or amount of fabric layers when needed for best looking and performing results and then just figure out what works and doesn’t work. Different speeds and stitches and stitch length and thread type and thread direction. Some machines are pickier than others with thread direction. (Some threads are made to be fed from the top of the spool others are meant to be fed from coming off the side of the spool) imagine the larger cone thread grab the loose thread and pull it straight up, imagine a small spool of Coats and Clark thread standing straight and grab the loose end and pull it parallel to top of table. Some people disregard details like this, I don’t, personally. Just because you don’t have a larger industrial machine doesn’t mean you shouldn’t strive for professional looking results. you’ll be limited to what you can do for sure depending on what you want to do, but always strive for the best and figure out how to make it perform and look the best. Every machine is made for something different, so just because you don’t have a $2k machine doesn’t mean you can’t make good quality items- just as it doesn’t mean a $2k machine can’t make poor quality items. Sewing isn’t typically a shortcut for many things, it’s a way to provide you a chance to make and/ or alter whatever you can think of. It also has a relatively high price for entry, buying fabric, webbing binding, hardware, thread, hook and loop, etc. Others tend to factor in their time as well- I don’t, most people who say it costs less to just buy what is made will gladly sit on their couch and watch tv a few hours a night. I prefer to design and plan and make my templates and patterns instead, so it’s not wasted time or time I should be paid for. It’s for me. But just as any tool it’s limited by your knowledge and desire. What you put into it is what you get out of it. But I hope you enjoy it and best of luck!
