We haven't grown out of Ikea yet. Honestly, we have barely grown out of gathering most of our furniture from city street corners; Ikea is a huge step up for us. And while we do aspire to someday having furniture that doesn't require an Allen wrench, we probably won't even think about it until our kids no longer play with Playdoh (let that be a lesson to you all).
So it goes without saying that I'm a big fan of Ikea Hacker, a blog that features people's modifications of standard Ikea products. Every now and then an excellent idea for kids' stuff comes through, like today's cute paintjob on the cheapie Latt table and chairs set, among others. And many of the shelving and storage hacks are perfectly suited to children's spaces (this Barbie-emblazoned storage chest is freakin' incredible)
