I have a Juki TL and have used Schmetz, Organ & Superior Threads needles with no trouble. The machine is not picky about brand but all that Peckish mentioned above regarding type/size of needle holds true, in my experience, as well. With the right needle type/size I've sewn through multiple layers of leather, cotton webbing, jeans, thick/sticky applique projects, etc. The Juki TL2200QVP Mini is a wonderful machine. I think you'll really enjoy using it!
