Yes I know we just had Thanksgiving, but it's coming............
Now I know why I've never made an advent calendar before; 25 of anything is a lot. I found this building in a Dover book on victorian architecture, but I needed to alter it for my purposes. I numbered each window (and the door), found toy clip art, placed them just right, etc, etc. (Time for a nap).
Now for the easy part. Download the house here and print it out on card stock. Download the toys here and print on the same sized card stock. Use the letter borderless page set-up on both.
chip board or foam core (optional)
With an exacto blade, cut 3 sides of each window, leaving one edge as the hinge. Don't open the windows yet. On the toy paper, place glue around the edges and between the toys. Place the two pieces of paper together and press to adhere. Trim around the building. Glue this calendar to chipboard or foam core, if necessary. Open one window each day; they each have numbers. (It might help to have a straight pin or toothpick handy to help open the windows.) Enjoy!
