try running some of your fancy threads through the serger--not sewing to anything just run them through---use these for couching on anything---beautifull as accents on Christmas things like table runners-- be sure to put the pressure foot down when doing this as tension is better that was---good way to use up some thread you bought and now wonder why---[not yhat I have ever done that]---you can run bulky threads and yarn though also in the loopers and make "new" thread---you can also put fusible thread in the bottom looper so you can tack it in place before you couch it on---[that could be a bit expensive on a large project] It's really fun to see what you come up with
