When you paint a room, put some extra paint in a jar and keep it handy for quick touch-ups. Don't use a baby food jar or it will rust. Use a peanut butter jar with a plastic lid. Just take it out and shake well and use a q-tip for quick touch ups.
This picture frame collage is neat. I love the font on the wall and I adore the famed initial in the middle. This would take up a good chunk of our huge living room wall so my wall won't look so naked.
