Okay - so quick and informal post. I just found an awesome app. It is called Artkive (like archive... Only with Art).
So I haven't actually used the app - but the reviews are decent. Basically the idea is to photograph all your child's work (artkiving) which you then can share, print on different products or even make a coffee table book!!!
I think the idea is genius!! If is currently FREE in the apple app store (as of the posting of this entry).
Check it out!
