I started one about 14 years ago and still haven't finished it, but hope too. If it is one of the more complicated ones, it may be a big project for an 11 yo. OTOH, if it's anything like mine, a great project for grandmom and gd together. Mostly the reason mine is still incomplete is that it required a dedicated fairly large space to work on where it needs to live until completed and I had to pack mine away for some reason or other.
Good luck! and post some pics.:-)
