Well I don't know what file format you guys like to take but I put it in jpg. Both sides are included in the one image. To make the coaster simply print out the image on a photo quality printer or your choice of multi purpose paper, presentation paper, photo paper or card stock. Once printed out, cut out the two images. Then if you didn't print out using card stock, glue both sides to a material like cardboard, formcore or matboard. A damaged CD works as well. A CD is the perfect size and I used one of the many AOL CDs I seem to get on a weekly basis. The glue I used was rubber cement, but other glues or adhesives could be used depending on the surface. Now if this coaster is to be used it is highly recommended that it be covered by some protective coating. I am still experimenting with that.
I am very happy with this design, but I am thinking about coming up with some variations of it. I was thinking along the lines of doing each main character or an event from the movie. They will also be in the same format unless I find a better way to make them.
