If you have not already checked out Potamitis Publishers, do it now. They have just released a series of Orthodox coloring books - a Synaxarion for kids. There is one book for each month, affordably priced at only $6.99. Each book contains roughly 15 line drawings of saints commemorated during that month, along with a brief paragraph about the saint in Greek and English. I ordered a sampling of them a while back, and they arrived in my mailbox today. They are beautiful!
