Several years ago - okay, 38 years ago - I taught beginner sewing classes at our local Singer Sewing Centers (remember those?!?!?). The first thing I did was to teach them how the machine works ("DON'T SNAP THE PRESSER FOOT DOWN!!!"). Then to practice stitching, I had them practice sewing using only a used/dull needle on paper. I had straight lines, angles, curves (gentle and not-so-gentle to gauge mechanical skills), circles of three sizes, and stitching a 5/8" seam allowance from a highlighed line drawn (it was a garment sewing program). The important thing was to get them used to coordinating foot pedal pressure for consistent speed (regardless how fast it was) and coordinating the position of the needle in relationship to the line. After looking at the papers, I could see exactly where they needed help and attention in the actual mechanics of sewing with a machine. In addition to sewing charm squares together (for potholders, table runners, wall hangings - maybe with fusible appliques!), I'd also suggest a tote/gift bag project, or buying a ready-made panel and sewing on borders. I suggest the panel because sometimes it's more important to the kid to make/complete something "big" like the person who teaches her does all the time; then, since they finished something "big" and I have their attention, we work on refinement skills and incremental challenges and skill-building. Hope this helps, and thanks for listening!
