I've been trying to function without a message center/calendar for the past 6 months...and it hasn't been working for me. I finally took the frames I was using in our old apartment and repainted them.
Finding the right place to put them wasn't easy, I had to put them in the hallway next to the front door where there is absolutely no light.
you can't tell but I actually embossed the paper in the two smaller frames using nice swirl stamps and sea foam embossing powder. I'm so happy to finally have a place to write down notes without loosing them:) I couldn't find a whiteboard marker so I bought a non-waterproof marker which is great because I can't accidentally rub it off but it comes off really easy with water.
