I actually would ask the instructors at JoAnn's if they offer one-on-one. It may not hurt to take a class to see if this is something that your daughters would enjoy (for sewing). It's a great way to bond together as a unit, too. I think the kids get a big charge out of doing things with the parent at these, especially when they bring home a project they can be proud of - and build on.
Then - if they do not offer one-on-one; I'd ask friends, family and co-workers. Usually, you can find someone this way that you will be okay with having with your children (for both things you are seeking.)
