DIY Lunchbox Bookends from Crafty Little Gnome here. Good idea, plus she is using the lunchboxes as storage. You could get lunchboxes that matched whatever the child or grownup likes or liked as when they were younger - Barbie, Barney, Transformers, Batman, Star Wars, etc… off of Ebay.
This blog is for my crafting alter ego. I did lots of crafts with my very artistic mother growing up and continue doing them with kids now. I love really good kids' crafts that hold their attention and mine.
