I also have ten grandchildren and three daughters. I made 13 Christmas quilts and we played Dirty Santa and they each chose (or stole) a quilt. My patterns were: tumbler (I made two with different borders), quatrafoile, ornaments clothsworks.com), presents (Flurry by Kate Spain), twisted Christmas tree, pinwheel, trees and pinwheels (Jovial by basicgrey), spring rain, Christmas trees quilt (Laurie Matthews) , big tree ( Tinsel by Maudee Asbury) and two others I don't remember the patterns. All were free patterns. Good luck with your project.
