Have a serger? Does it sit unused most of the time? Use your serger to overcast the raw edges of fabric yardage before prewashing. Not only will you save yourself from the tangled mess of threads and fabric that comes out of the washer and dryer, you’ll also save your serger from an early demise. Machines like sergers with many mechanical parts can actually be damaged by not using them regularly. Essential lubricating oils inside the machine can thicken up and settle over time, which could cause moving parts to freeze up the next time they’re used. Fire up that serger periodically to keep it running smoothly and protect your investment.
