oh no!!!!! i've had a similar feeling, but about wallpaper and a certain son of mine!
I'm so sorry she did that to your hard work (and love that we mamas put into those clothes).
I'm thinking, if it were my 5yo, she would have to live in dad's white undershirts and one pair of pants for a few weeks since she can't take care of her clothes. and NO scissors for EVER, or a year, or some length of time that would feel that way to a 5yo.
I like the advice to sew for the others and strike on making her anything.

poor mama
