I have a Babylock Ovation and a Babylock Synphony. I made teeshirts and swimsuits in the early 70s for my children but gave up- Too bothersom with my 99k singer and the old zigzag attachment. I want to use my machines' capabilities. Will you be covering using "knit stitches" and serging also? I've been sewing since 1967 and am rtaking Craftsy classes to modernize my skills and learn new wys of doing things.
