Janome Janome MyLock 644D

The MyLock 644D is a serger that switches from overlock to rolled hem with a single dial, without changing the plate or the foot, and thread tension optimizes itself when you switch between stitches. It sews with 2, 3 or 4 threads, with a 2-thread converter that attaches when needed, and the lower looper has an assisted threading guide for anyone still learning the thread path.

Differential feed adjusts from 0.5 to 2.2, stitch length from 1 to 5 mm, and cutting width from 3.1 to 5.1 mm: enough range to handle light jersey as well as sturdier fabric. The waste collector is standard, useful on long seams. It's a machine for people who finish edges regularly, not for decorative stitching: that stays outside the scope of any serger.
