Under the glass of the frames she laid strips of scrapbooking paper in them with circle punches and letter stickers. Voila, a weekly planner showing this week and next week, that I can write on with dry-wipe marker:
Paint swatches framed behind glass to make a dry-erase calendar. I would make a weekly calendar and use a different color for each family member. You could even mark your recurring commitments (dance lessons, work schedule, etc) under the glass so that you don't have to re-write them every week. It would be easy to swap them out if something changes.
