Here are two of my favorites I did keep. The first one is housed is a gorgeous stone frame. It's quite large and heavy, and I kept it on my mantel until just a few months ago - would move it at Christmastime, but for the most part was always there. I now keep it on the wall above our sofa.
This second one is a wonderful small sketch surrounded by handmade paper in a muted painted silvertone wooden frame.
