Singer 15-91 needle question
Finally got my machine back from re-wiring and maintenance. I can't tell by the book what size needle I should be using for piecing. What do you all usually use and is 50 wt thread what you use in the machine too? Also, should I just use Singer brand needles? There's definitely a learning curve for me since all I've ever sewn on are modern machines but I'm excited to have this one!
