I made an I Spy Bag for my grandson's 5th birthday present. There are 50 small items inside this beanbag type pillow that is filled with plastic pellets. He can look at the laminated picture card with the written list on the back for when he starts to read.
Kids love to look for the hidden objects in this seek sack. It is perfect as an activity for the car. This is a page about making a seek sack.
