I think hands on is usually best for everyone. I know where I live I teach Embroidery Club every month and it is free. We also have embroidery retreats every couple of months, where you spend the whole day with us and sew a number of different items. A great way to learn. So if we do this in my area, I would think something like this might be available in her area as well. Maybe online tutorials? Just thinking out loud. Best of luck
