If the step sisters are 19 and 21, how old is Maggie?
That was five years ago, and her hands were pretty small, so she can't be more than 13 at the most?
Her steps are adults (in age) for pete's sakes!
How loving of you to make a new one and to let Maggie help you with it. She is never going to forget what a wonderful, wonderful grandma she has. :-D
