I know lots of younger quilters...I am 52 and definitly the senior in our little piece of the world.
My son was 26 when he started quilting, my nephew 22, his girlfriend 18, both of my granddaughter's finished quilts before they were 10...my youngest granddaughter made her first quilt out of her own stash when she was 4 (to send to her daddy in Iraq) it was twin sized and she stood on a dresser to quilt it herself on my big machine.
any girl (or boy for that matter) that has any interest in fashion or anything to do with textiles should be happily experimenting with color and fabrics making quilts, we encourage all of the young people to jump right in. they are very receptive. I have a family friend with 5 little people...as each of them enter preschool we (the class, teacher, assistants, and myself) create a new quilt to make and raffle for their end of year field trip and we make one for the class, the kids LOVE doing this!!! and the boys are better at most of it than the girls... :mrgreen:
