Compulock The First Serger Easy Enough To Be A Memory Craft. As a Memory Craft, the Compulock features a large, interactive Visual Touch Screen which displays timely information and - in turn - registers your input and selections.

You can page through a menu of built-in-stitches, consider recommended settings, and recieve messages - using many of the same screen navigation keys you've used on your Memory Craft sewing machine. From over lock to flatlock to overedge to rolled hem to picot edge to safety stitch, the Compulock has it all. Fifteen primary stitches plus six variations - a total if 21 built in stitches - more than any other serger on the market. And compulock cover stitch 6mm wide, giving your homemade garments the look of expensive ready-to-wear.
