April is National Serging Month - a month meant for Baby Lock! Baby Lock sergers are the BEST sergers on the market. If you haven't seen Air Threading, you don't know what you are missing! With the press of a button, and a burst of air, your loopers are threaded in seconds! No tweezers and magnifying glass are needed to get a Baby Lock serger threaded. And, most models have Automatic Thread Delivery, which means you don't have to set thread tension manually - you get perfectly balanced stitches every time.
