Do ye hereby agree to lead your crews in crafting jolly-good treasures? Here be the rules: No junky, toss-away-next-week crafts! No girly-cootie stuff! No mine-looks-just-like-yours projects!
Aye, now, when your crews have sailed far from Clapping Rock, they will again admire their treasures. And each time they do, the Bible story linked to the craft will leap back into their minds. You're not crafting treasures; you're creating links that will lock the Bible stories into your mates' long-term memories.
