Christmas is fast approaching and if you are planning on doing a customized photo gift, now is a good time to start. The last two years I have made customized calendars for several family members. Grandparents love a calendar full of their grandchild(ren). I have mine printed at Costco. I found they have the best prices; however, there are lots of other great sites you can use.
I design my calendar pictures in my design program just like a scrapbook page. See this post for more info. If you don't have a design program, you can still do custom calendars, you'll just have to use the sites pre-made templates.
Here are some calendar pages I've done in the past to give you some ideas.
