The BERNINA Zippered Leaders have many benefits for the quilter, especially when working on more than one quilting project at a time. Instead of pinning the backing and lower end of the quilt top directly to the leaders on the frame, the fabric is pinned or even machine basted to the respective smaller zippered parts of the leaders and then zipped onto the main part. This can be done in a comfortable sitting position. Additionally, the quilting project although unfinished, can be changed with ease zipping off one and bringing on another. The started project will remain square and can easily be put on the frame again with just a few steps.
