DESC: Get ahead of the curve with the Singer 8763 Curvy Electronic Sewing Machine. Sew smart with its SwiftSmart threading system and Drop & Sew bobbin system. Its Digital technology makes threading a cinch. All you have to do is guide the thread directly from the spool to the needle area through a single groove. Then the needle is automatically threaded by pressing the Threader Lever. Three lamps illuminate the sewing surface with long-lasting bulbs (100,000 hours) that stay cool, regardless of how long the machine is operated.
