Wow! We found Gutermann industrial quality Mara 120 thread perfect for bra-making because its fine size will allow the stitches to virtually disappear into the fabric. We bought colours that match our products. Beige is an especially hard colour to match but ours is perfect with our Duoplex, Simplex and other beige fabrics. Each cylinder holds 1000 meters (almost 1100 yards) and can be used on either domestic or industrial machines. Quality is superior to the brand sold in fabric stores.
