Since moving into our new home, we have to admit that we have a handful of framed artwork that's still leaning against the bedroom wall. We haven't gotten around to putting them up because (while we love the frames) it's the artwork that isn't jiving. It's a matter of the old artwork not living up to our new decor and the fact that our tastes have slightly changed.
Violet also had this same experience but instead of sending her artwork off to the framer--she decided to update it at home. After removing the old print, she chose to use a textured heart for matching frames which gives her living room a fresh look. Using string and a hot glue gun, she simply affixed the heart to the frame and put the piece back together. Such a simple DIY using things you already own--love it!
