Nonny, we have 8 grand children and only 2 boys, all the girls are teenagers except this one. Our older grandson is also 11. I haven't knit him much. I just made him a hat for his birthday. His mom said his favorite color right now was purple, so I took a chance on a royal purple slouch hat. I heard he grabbed it saying, "Purple", and put it on his head. I don't know if he liked it once he saw it on.
I tried. They can be very opinionated.
