Faux tin tiles from Lowe's or Home Depot sprayed with coordinating colors for a cheap accent wall. I love the idea of this as both an accent wall or as a ceiling in a turn-of-the-last century room that originally had tin or brass tile ceilings.
Another awesome art project to do with kids over break: On your next nature walk, have your little one help gather acorns for mommy's next project! With this simple How to Paint Acorns craft, you can create some stunning fall decor! From J Hunter.
