The 1110DX Pro makes serger sewing easy! Incorporating the differential feed system of two feed dogs, puckered edges on woven fabrics and stretched edges on knits are virtually eliminated. The rolled hem conversion feature eliminates the need to change the needle plate, foot or tension setting for rolled hemming. Restructured lower looper guides allow easy access. The included threading card and color-coded guides are easy to follow for 2, 3 or 4 thread serging.
