My 12 year old was a little boy when I made him and his brothers D9Ps of their favorite cartoons. He's since grown out of it and needs one bigger bed size. He's asked for the same pattern, but Marvel comics instead of Thomas the Train. My 11 year old is also due another quilt. He's looking through a list of patterns I have gave him to pick one for his bed and he agreed that we could pick the fabric together. He isn't interested in a D9P or having Lightning McQueen on his quilt. I think each one is different. My 11 year old is very interested in the process of going from pattern to quilt, so I'll include him in the process and see if the quilt bug bites.
