Patented differential feed for ideal control of gathering
With the BERNINA 1150 MDA, puckered or wavy seams in knits are a thing of the past: a simple turn of the dial adjusts the patented BERNINA differential feed to the material in question. This clever feature allows you optimum control over the feed, effectively preventing unintentionally wavy, puckered seams. Should you wish to gather the seam, the gathering process is infinitely adjustable with a simple turn of a knob. This lets you use the 1150 MDA for impressive creative techniques, where you alone decide whether and how much to gather your seams.
