Query: Great project for kids 9+

I bought the Knot a Quilt for my 6 and 8 year old for a long car drive hoping to give them something to do. They loved the idea of making their own blanket, but had a hard time doing it for a long period of time without any help. My eight year old had a little trouble with it, and my six year old needed help with keeping the knots in order, it was frustrating for her.Overall, they liked it but I would recommend it for 9+ age group.
