I think you have created a monster, but I bet she's adorable. She definately has talent (like her Mom) so I think it would be a good investment to get her a machine of her own.
I love to hear about children wanting to learn to sew. You are fortunate to be able to share this with her. You might want to sign her up for JoAnn's flyers ( to get coupons) ..she needs a stash. (Yes, I am an enabler ♥)
