I did like that idea but did not want to buy twenty plus little boxes with the cute train on them.
I found a package of twenty small blue circles of toule precut on clearance for 50 cents. I found a cute graphic of animals on a train and added the text to say animal crackers. After cutting out the tags and backing them on blue paper, I tied them on the blue toule circles with some decorative brown ribbon (On sale at Michael's for 50 cents). Basically all of this including the animal crackers came to a whopping total of $3.50. Much cheaper
and time consuming then Barnum's Animal Crackers.
