Here's a pic of the kitchen hubby made out of a side table from Ikea.
We got the idea from Ikea Hacker and the rest is history. Much better to use actual materials then plastic! Most of those kiddie kitchens are made out of plastic and are just not good for your kids. Consider options like this made out of wood, paint or stain with eco-happy options and you have a family heirloom that hopefully can span generations. Ok, maybe I'm being a little over the top, but you get the idea!
