So I decided to make photo collage thank you notes. I took the picture(s) of each child opening their gift and made it into a thank you card for each person. Wal-mart.com makes it super easy and quick to make up these 4x6 collage prints so you can include more than one picture and a small caption. It cost me just a little over $2 to make 9 of these cards (that is including the cost to have them shipped to my home since we live 30 min away from Wal-mart and it wasn't worth the gas to make a separate trip to pick these up). When we lived closer to a Wal-mart I would order them one our photo and be able to have Scott pick them up the same day at the store. Or if you aren't in a hurry you can order then and have them delivered to the store for pick up (which is the cheapest way). Anyway all that to say they aren't super expensive and each relative who sent us gifts gets a thank you note with pictures of the children opening their gifts.
Here is a picture of how they turned out.
Oh and for any family members wondering where their thank you cards are they should be sent out in the mail tomorrow :)
