I wind my own. They never seem to have the colors I want and I don't buy that many. I use what ever thread I like. My machine is not too picky. I seem to gravitate to Permacore and Omni ( look like cotton but are poly wrapped poly) and Glide (trilobal poly). You will need to try a few and see what you like and what works in your machine. I find that cotton is VERY linty. My machine does not like lint. I started with a used machine so I jumped in with no classes at all. There WERE tears. I have since upgraded and took all the new owners classes that were available. DVD and good manuals are invaluable too! Half of what they tell you will go in one ear and out the other! Find someone you can call to be a mentor. Good customer service is a must. Good luck on your journey!
