The best thread to use is smooth polyester. Serger thread is not recommended. Using quality thread will help your quilt be a success

Set the tension with the dial. Tension depends on how fast you quilt and the thickness of your batting, as well as the thread you are using.

Thread the machine in the order shown on the diagram. the needle should be threaded front to back.

For the two hole tab on top of the machine, put the thread through one hole. it doesn't matter which hole. The second hole is only needed if you need extra tension after adjusting everything else for specialty threads and can generally be ignored.

The three hole tab should have every hole filled in a spiral pattern. the first hole can be skipped if less tension is required after all the other options have been tried.

the color of thread can be changed by cutting the thread and tying a knot to the new thread, then pulling it through.

Cotton, poly core, invisible, and metalic threads can also be used. Thin decorative threads may be easier to use if doubled up, using the second spool holder.
