I received several small chalkboard signs from a friend's sister that were used at her wedding that we'll use for our wedding, plus a large chalkboard that we'll use for our seating chart. All items have things already written on them in chalkboard pen. Is the best way to get rid of the writing to just chalkboard paint over them, or is there an easy way to get the chalkboard pen off without having to go the paint route? Any tips/tricks from those that have repurposed chalkboard signs is much appreciated - I'm craft/creative but I don't do it too often so my skills are forever rusty.
