Well being a beginner still I have some thoughts. definitely find out what she wants to learn. I was Taught to hand sew so I am just learning to use the machine so with that in mind showing her the parts of the machine and how it works would be great.
For the rotary cutter I think the first few tries could be with paper then moving on to scraps or fat quarters ( I am still nervous when cutting large pieces of fabric :oops: )
Basic design would also be good I would maybe even start with a 4patch or rail fence.
I think you already have a good idea of where to start. I guess the most important would be making sure she is interested and not being made to do this and keeping her interested. maybe once you get her making blocks you could use them to make some doll quilts or small tote/handbags.
I am taking a sewing 101 and the thing I like best is that after a 2hr class I leave with a small finished product to show for it :lol:
well hope I was a little helpful, sorry it was so long :wink:
