I don't think you need me to explain why I like these things :), but I will say a little something about number three. It's an office made up of elements from the elfa system - a line that's carried exclusively at the Container Store. Elfa is an amazing system that you can fully customize to fit your needs. They have systems designed for everything - closets, kitchens, offices...you name it. It's brilliant. I dream of having an elfa system in our house one day. And I've got a little tip for you in case you're looking to add something like this to your home: they're having a 30% off sale right now. This only happens once a year, so jump on it if you're interested! (Disclaimer: I'm not being paid to say this. The Container Store has no idea who I am or that I'm posting about this today. I just love the stuff and like to share a good deal when I see it!)
Oh, and a reader was asking about a source for washi tape after I posted about it last week. Click number eight to see The Container Store's selection. I know you can find it on Etsy and I've heard Target has some too, but this is another resource for you!
