I made labels for my lists, and matted them on Stone Grey linen paper. I adhered these directly to the 12x12 sheet.
Although I wanted my calendar to have glass on the front, I quickly realized that the magnets wouldn't work through glass, so I moved on to 12x12 sheets of clear acetate. Before adhering my acetate over the calendars, I added a few stickers to the calendars that I wanted permanently adhered under the plastic. Then, using tiny glue dots in each corner, I adhered 6 sheets of 12x12 clear acetate over each calendar and the list sheet.
