Years ago a neighbor ask my Mother to teach her to sew. Mother sent her to the store and told her to get a pattern,read everything on the back and buy what it called for.
She came back to Mother then Mother told her to get out the instruction sheet and tap it to the wall over her machine and do exactly what it said. She was so mad at Mother for not looking over her shoulder she wouldn't speak for a month. She did finish the dress and in six months she was sewing for the public.
That is the best way for a beginner. Then they will take off on their own
