I love calendars, and I love to make them. I could spend hours just drawing out days and months and years and planning to my heart's content. A few months ago, I made a "reusable" wall calendar to capture our family's day-to-day schedule. I used a glass whiteboard from Ikea and made a calendar template with white vinyl. At the beginning of each month, I just erase the contents and rewrite the next month with a dry-erase marker. I placed another glass whiteboard below which I use for To Do lists. There are several clips down the side which I can use to clip upcoming wedding/party invitations, coupons, etc. I also try and take a picture of the calendar at the end of the month before I erase it so I can use it to help document or record what was going on in our lives during that month.
White Vinyl - I used my Silhouette to create the white vinyl strips.
