WE ARE ALWAYS HERE TO HELP- According to our test,we found that it will be better to use #14 needle to work when you use our glow in the dark embroidery machine thread. Normally we use #9 or #11 needles to work when we are using polyester thread. But we'd better change a larger size needle when use this glow thread. Or the thread may get a break during its work. Anyway,we will always do you a favor whenever you get a problem and contact us.
