Ok guys, I've got a puzzle piece I don't understand. I have 8 inner stem pieces made of cedar, and 8 outer stem pieces made of cherry. Where do these go?

I thought I knew until I saw there are 8 of them. I thought there would be a piece of cedar on the outside of the bow and stern (2 total), and on top of that a piece of cherry(1 on each end, for 2 total).

Confused,

Woody
