Thanks, everyone! What a busy board this is! I didn't expect to get so many responses. I think I will just bind it, as this will be the first major project I've tackled. Also, it seems clear that that's what she intended to do herself, and I agree with the others that it would be nice to keep the quilt close to what she'd planned. I'm definitely leaving her stitches -- I don't think I could bring myself to tear hers out. What do y'all think of adding the X's and O's (or hearts, perhaps?) to the squares, though? Like I said, I'm not sure how the X's will look on the solid-colored backing, since the squares don't match up exactly.
