Free-motion Quilting, I am finally getting the knack of this! Love using this foot to see my entire stitching area! BERNINA’s Embroidery foot #15 is for many kinds of embroidery, but I use it most for my free-motion quilting! Its vertical spring-loaded mechanism prevents the fabric from pulling up with the needle. This ensures neat stitching for me! I love to do Baby Charity Quilts for our local Charity and learning to use “#15” has helped me so much. I can now stitch elephants and birds and in my photos: “BUTTERLY’S.” Thank you BERNINA for such beautiful quality “aides” !
