As an end-of-the-year thank you, I took pictures of several of the projects that our 3 year old made throughout the year.  I took pictures of each of them on a white background:

Then, I cut them out in Photoshop and combined them into a single file.  I printed it on greeting card paper.  It was a great way to say thank you for all of the time and planning that she put into all of the projects they made throughout the year.

Also, see how we save and display our kids' artwork at home.
