what a great thing to share with your GS! He will treasure that quilt forever - and his memories of making it with him. Both of my boys can sew, they are 10 and 9, and the younger one loves it. Both will have a twin quilt hanging in our guild show this fall. One thing to do is make sure you are teaching them good habits - I find my younger son sews like I do - and I throw thread on the floor of girl cave. Which I learned from MY mother! Now, how am I supposed to have him put his threads in the thread catcher!
