I introduced her to the basics of using a sewing machine, how to thread it, wind a bobbin, needle up/down and reverse. I explained tension and stitch length, thread weight and needle size, she sewed a few test samples. It was wonderful teaching such an enthusiastic student!
I explained terms as we went along, fusible interfacing, right sides together, seam allowance, pivot, clip the corners, turn and press, top stitching. Her excitement at learning something new and making something fun and pretty fueled her energy to continue.
