This is by far the most special project I have been a part of. When my father asked for a photo collage of all his grandchildren, I knew immediately what we should do and called my other "Martha Stewart protege" sister, Jessica. She was instantly on board. We consulted our other siblings, who all agreed.
Even though we all live far apart, we each undertook an element of the project to make this come together. Luckily, we had ample time to prepare and complete this enormous collage. We all agreed to have this ready for his birthday - more than half a year later. At some point, I am sure our Dad assumed we had forgotten.
Finding an old french door with 18 window panes was a challenge, but eventually the right one came along. If needed, we could have grouped sibling children together for some of the photos. We might have to do this in the future for replacement photos if more come along.
