Promotional materials for Bible School are online

Yesterday we worked on a poem that we intend to use as a dramatic reading in the church service, to announce Bible School to the congretation. We also finished up the fliers. So this morning I put our promotional materials online, or, at any rate, what we have done of them thus far: the poem, the poster, the fliers, the invitations, and a sample invitation letter similar to what we plan to mail-merge.

Any additional ideas for things we can do to help our congregation get excited about inviting children to Bible School this summer?
