Do you ever see those big spools of thread for the serger and wonder...'Does serger thread work on a sewing machine?' They can work on a machine, but only if you have one of these funky looking gadgets.
I dunno what they are called, but I found mine on the notions wall at Joann's. I know it cost around five bucks with a 40% off coupon. (Or you could get it when their notions wall is 50% off or BOGO.) Using serger thread is much more affordable. I usually buy most colors this way, then have the smaller spools for colors I don't use as much.
