Ben 10 is my son's favorite TV cartoon show and an ongoing obsession. So when he asked me to make him a jacket like the one hero wears in the cartoon, I hurriedly complied (he was moving on to the various alien costumes). Ben 10 seems to be quite a favorite with the boys this age, as I discovered many similar projects at ravelry. One reveler even shared her intrasia chart which saved me much time and grief.
I don't have to tell that this sweater is a resounding success. My son would like to wear it all the time. He also went off to show it to his grandparents, who had no idea what or who Ben 10 is. Even his little sister has been trying it on. As for my hope that it will be the only piece of knitting based on Ben 10, that seems to be futile thinking as I am already receiving requests for one more. Maybe next year, just maybe.
