I give you the Stephen King star garland. One of his paperback novels (translated into French) has been lying around for a while at work looking for a new owner. Now it got sacrificed for a good cause. I made two identical stars like these and put them together with scotch tape. Then I hang them up with yarn. I don't have so much storage in my small apartment so I can't have a lot of Christmas decorations lying around.
I bougt the blackboard and the whiteboard weekly planner you can see in the background in Sweden by the way. It was in our 60kg of luggage.
