Mighty fine bows there superDav
My experience with kids is they are very excited at first but many will be soon carried away by other interests
In many cases it's a waste of time and energy doing a work of art for kids.
They simply are unable to appreciate it.
If you spend enough time with them you'll eventually find one or two that get really interested and that's when it's worth to give your best
.... and yes I'm frugal too
