As combining rows of loops makes knitted fabrics, there is the possibility that the needle can destroy loops. In choosing a proper needle, it is absolutely necessary to find out the correct needle size and point form.
Please use KN-needles, which have small ball points (slim balls) to minimize the penetration resistance and avoid thread breakage. They also have a special form of clearance above eye to make easier loop formation and avoid skip stitching. In addition, please check the needles periodically for wear or damage, especially the point and spot area.
