When my husband and I first got in engaged, it was right around thanksgiving and we ended up planning a November wedding. I wanted to make a save the date that was useful and unique. I took inspiration from a calendar I picked up at Hatch Show Print when in Nashville a few years before- they used their test prints and extra prints as the backing to their desk calendars. We sent them out with our Christmas cards that year so people could use the calendar the following year and start to use it right away. Our wedding date is circled on the calendar as well.
