The benefits of this Maxi-Lock® Natural Stretch Serger Thread are endless! Finer than the average thread, serger threads are smooth, soft and strong. This particular Maxi-lock is ideal for knits and leggings since it allows your hemlines and seams to stretch with your piece. Two thousand yards of 35 weight 100% textured nylon thread are wrapped around a cone spool for easy use. Ideal for overlock and serger machines, this collection comes in a wide variety of colors.
