DIY Tutorial - Yarn Wrapped Star Ornament - This is so cute! A great way to use up left-over yarn, and I'm pretty sure that lower-elementary kids could help with this. For starters, they could draw the stars!
Watercolor on book pages -- I really like the idea of doing this. Would be really easy to find a random book at Goodwill on the cheap and use it like a "practice" art journal. Frame for holidays or art!
