GREEN UNDERTHREADS
They may be only be visible on reverse side but underthread is one of the most important factors in producing high quality embroidery. Often overlooked in embroidery, good quality underthreads wound at even tension will assist in the production of the perfect embroidery.
For standard length stitches the general rule for underthread requirement is approximately 3m per 1000 stitches. Top thread you can expect approximately 5m per 1000 stitches. A perfectly tensioned embroidery with standard length stitches should have 1/3 bobbin thread to 2/3 top thread visible underneath.
