Go on HQ website, or YouTube and google TNT - threads, needles, tension. This will answer many questions you may and may not have. Your HQ does NOT use the same needle as a sewing machine, the shaft is different and it has a thread groove in the front. Try using as thin thread os possible which will make it possible for you to use a thinner needle. If you are willing to take your basting apart, double layer the batting - thin black on the back, thin white/natural on the front. I hope you get this resolved.
