Thanks for the ideas! It's just what I needed. She does have tshirts that he wore. I haven't brought it up as I just wasn't sure of the expense part of it. I didn't want to get her hopes up and then it be super expensive to make it.
I'll ask her if she is interested, then if she is get the shirts and see how many/size.
I do have some stash that I would most certainly use, just not a lot, but maybe enough that the quilt wouldn't be prohibitive.
Thanks ladies!
