Build Your Own Baby Gate. This is great for the bottom of the stairs, or the top, if you used a more child-proof latch design. Maybe just putting the latch on the side the kids aren't supposed to be on would keep little fingers from opening this. I REALLY love how it looks--and it's really just a half door. Perfect.
Salt Dough Santa Handprint Ornaments: 1/2 cup salt, 1/2 cup flour, 1/4 water (give or take), knead until dough forms. Make impression and cut out hand shape with a knife leaving a border. Poke a hole in the top for hanging. Bake at 200F for 3 hours. Paint, seal and ready to hang :)
