Here are some ideas.. i have to think about this as well bc I will be going to visit my new greatgreat grandlittle and a new great gradlittle soon.. my litte ones are so great.. i talk to all of them like everyday!!!
Last year for my great-grandlittle I made a photo album.. I got fabric and covered a photoalbum.. then put pi phi wooden block letters on it.
You could also make one of those photo ribbon things.. cant really think of a name for them.. haha but a bunch of sisters have made them in the past..
Also I know another cute idea.. i got this idea from a friend of mine who makes her own mirrors.. well you can buy a cheap framed.. any size.. mirror from say walmart. Then get that plaster type stuff and mosaic tiles in pi phi colors from the craft store.. then put the plaster stuff around the frame and then mount the broken up tiles on there.. hopefully this helps a little with the idea.. you can go to the craft store and figure it out there better
