Not if you ask her NOT to - she can go around your stitching, so as to not damage any of your stitches - might work out better for her too - so she doesn't have to worry about snagging or catching your stitches. If there is enough space in the design itself for her to do some stitching of one design or another, then you wouldn't have to do any hand stitching or tying, as 12" is too large of a space to not do something to it.
