Don't push her, if this issomething that she wants to do then she will. I have had a sewing machine since I was 10. Then when my grammie past I got hers, but it wasn't until about 4yrs ago that I started sewing. I had a friend who was working on a table runner that got my attention.
So give you DIL a little room and if its meant to be, it will take off. If not her then maybe a grandchild.
Good luck :-o :-o
