It wasn't for a number of years that I took to making a collage for the kids' birthdays. The first, him at age 4 and her at age 6, featured photos from all of their years. Nows, I just use photos from the past year. I don't know how long I will keep doing this as I somehow imagine that there will be fewer pictures as they grow, but we shall see.
I also have been making my own cards. This is the card for this year: front (and back) first, then the inside. I used some humour on inside of this one.
Below are the collages from the past two years.
