The Euphoria coverstitch machine from baby lock is in a class of its own. Of course, the Euphoria also has the familiar baby lock features such as an automatic thread delivery system, air threading system for the looper and a needle threader. But now with its wide throat, you can now coverstitch to decorate even large pieces of fabric. The knee lift is an additional aid for more difficult projects. It leaves your hands free to guide the fabric reliably. Simply lift and lower the presser foot with your knee.
