All of these projects were for books used by children at Vacation Bible School, which is a children's program used by churches in the summertime. The books ranged in size from 4.25" x 5.5" to 8.5" x 11", and were divided by age into four groups (ages 3-5, 6-7, 8-9, and 10-12). Each year a different theme was introduced to make the course fun and exciting, especially in these student books.
