If you are wondering how to make this, it's super easy and inexpensive!
I printed a 20" x 30" enlargement of our printable file at Sam's Club. It was ready in an hour and cost less than $10! I used spray adhesive to mount the photo on to a piece of cardboard. I then cut out the hole for the face using an Exacto knife.
Helpful insider party tip, I had fun prizes ready for each child after they got their picture taken. It was great motivation to get everyone to show their fishiest faces for the camera!
Fish-In-A-Bag Soaps made great prizes!
