I made a few baby hoodies and wanted to learn to insert a zipper into one of them. I was pleased with my first attempts and will do more closures this way. My notes are in Machine Knit Techniques; Misc Techniques in the headings above the blog title. It seems like a lot of hand basting, but it is worth it to get all the edges even. Because it is so visible, being front and center on the sweater, I wanted it to turn out well.
