Suggested by the manufacturer of what...the machine or the thread? Needle size and type are determined by the thread and fabric being used. If the eye of the needle is too small for the thread, the thread will break whether it's new, old, hydrated, dry, oiled, or not because it's rubbing on the edge of the eye. The eye of the needle should be 40% larger than the diameter of the thread. The groove should also be large enough to contain the thread.
