I missed the original post, sorry! I haven't been doing this very long, and I also don't like my own handwriting, and I also can never think of what to write. I've only made one full book, for my sister, and a few pages in a new book I'm working on.
For my sister's book, I had a lot of old photographs in boxes with no dates or anything on them at all, and I thought it would look half-assed to write "Me and Leah at some place somewhere, sometime maybe in the
80's, I think" and stuff like that, so instead what I did was I found cute or poignant quotations online to go with the pictures and printed them out from my computer. There are lots of quotation databases on the web where you can search by subject. If you want to see the book, it's here:

For my latest book I have some pictures of my nephews, and I made a list of what each of them is into at the moment.
