After sewing classes, more time to participate, I bought a serger in January, difficult machine to use to tell the girls sewing, with this belief, I left aside until mid-May, surprise because easy to put on and take main.Par against the seam guide is essential because very well done with photos and clear explanations, for me novice, this book shows all uses of the serger not listed in its user guide, I am still surprised at all the possibilities achievable through this book.
