splitting thread
 

I am new to free motion quilting and have been just teaching myself along the way. I have a problem with the upper thread on my maching splitting. What am i doing wrong?

two guesses:

tension needs adjusting; or
wrong size/type needle

i consult these articles when i need to figure out which needle to use with which thread:
