WonderFil pre-wound bobbins are wound with our 80wt DecoBob thread in a reusable plastic bobbin, which means there is no glue or wax holding it together (which also makes for happy machines)! DecoBob makes for an ideal bobbin thread as using a finer weight thread will also minimize the bulk in whatever you are doing, however DecoBob also has the strength, versatility, and reliability you can count on.

Pre-wounds are a fantastic choice because they come wound uniformly meaning you will get more consistency in all your stitches, which is especially noticeable when doing embroidery. They also come wound with a higher density of thread than when you wind your own bobbins on a domestic machine.
