My sister-in-law put together the cutest memory display for my niece's 1st birthday party. Check it out:
Sorry for the photo quality. The camera on my phone doesn't take the best photos.
Each picture displayed a picture of Sadie at month 0-11 and was clamped to a ribbon by mini-clothespins. Adhere the numbers representing how many months old she was when the picture was taken and a few decorative circles with her initial on it and voilà ... a wonderful walk down memory lane.
