When working with Zigzag Hemmer #61 the fabric is fed into a scroll, which turns the edge under twice. This prevents the fabric from fraying later. The guide holds together the turned hem until it reaches the needle.
The fabric edge is then sewn with a zigzag stitch into a narrow, sturdy hem which advances easily under the foot.
Please note that this price is for a new style Bernina. If you want the price for an older Bernina please contact us with your machine model number.
