I found the initial idea for this craft on instructables, but I modified a few of the instructions. Basically, its a photo that I took and "blew" up to a 12 x 12 image. Its nine pieces of the picture printed individually on tissue paper, then ironed to plain white tiles. the nose is slightly off balance because I didn't line the tiles up perfectly to take the picture. It's of my gorgeous mother on her wedding day.

I changed a few of the instructions- I ironed the paper on instead of gluing it, and I added a sheen to it with a spray adhesive. I used Gimp (free on google) and divided the picture into nine parts by making the grid at 33% and 66% for both vertical and horizontal, adjusting if the line landed at the eye.
