Sylvie's Storage Baskets: Another Ikea and Land of Nod mashup. $12.99 Ikea Lack tables combined with big Land of Nod storage baskets (a perfect fit under the tables) makes for hidden but easily accessible storage.
Easy Canvas Bins, Old School Ikea: Chiara says that these Ikea storage cubes are over 25 years old (bought for her when she was a girl - the new incarnation is the Expedit) and turned out to be a good fit for canvas bins from Land of Nod. Round paper tags help identify the contents.
Super Duper Closet System: Ikea's Antonius system combined with Ikea plastic bins organize a closet that was first painted a bright cheerful hue (Lobster Bisque by Martha Stewart). Finished with a curtain instead of a door to save space and open things up.
