Wall uglyness

So I'm back at work now - 3 days per week and I must say that it is causing issues with the regularlity of blog updates...sorry post a day in May.
My office is brand spankin' new. New chairs, desk, shelving, carpet, computer etc. The walls are bare and I'm in need of a wall planner. But I don't want one of those ugly ones that you get through the office stationery suppliers. Any ideas or recommendations?
