O.k. ladies...so my niece asked me to make an extra buttonhole on her semi formal dress because the straps are too big. She's 15 and saw my sewing machine out (because I've been quilting) and as kids do she thinks that means I can do anything! Lol. So, I've been practicing buttonholes for the past hour I've some what figured it out except I can't get the hole guide to sew the new buttonhole at the place I mark....any suggestions??? It keeps sewing the hole above where I mark. Help please?
