We also had an old book that explained how to use each one, and dispite complex diagrams and long lists of parts and their functions, they were actually fairly simple to operate.
I am particularly excited about the four hemmers in the kit. I can't wait to easily sew hems with those handy little attachments. I did try out both the ruffler and the narrow hemmer, and was very pleased with the results.
The ruffler was especially fun to figure out, and I love how adjustable it is. It ruffle or plait, scantily or heavily, close together or far apart. And the Narrow Hemmer did a seam fabulously and easily.
