My IKEA Raskog Cart currently holds all of my planner supplies and resides right next to my corner desk. The best thing about this cart is that because it has wheels, you can literally roll it wherever you want. If I want to do some planning at my desk or in bed, I just wheel the whole cart right on over.
I did add a few accessories to be able to organize my cart abit more including a clear bin from The Original Scrapbox Tote Upgrade Kit to hold all of my Happy Planner Sticker Books, small mint plastic magazine holders and cute polka dot tin buckets from the Target Dollar Spot a few years ago. The polka dot buckets are held onto the cart with some bull-nose clips and contain all those little odds and ends you always need quick access to like Frixion Pens, Frixion Highlighters, Post-its, and extra washi tape.
I do know that the mint color cart that I have is no longer available from IKEA but I did see a similar one being offered at Michaels. The other great thing about this cart is its versatility. Before holding my planning supplies this cart has also held coloring supplies, die cutting supplies and Project Life Cards. This cart also makes a great make-shift cart of things to do when you are laid up in bed after a major surgery. Don’t ask how I know that ;)
