My lowly interpretation using our newest kit Caboodle!
duh: here's the basic instructions!
The pattern is basically:
4 sheets 12 x 12 cardstock
Score on each end at 6"
The bottom left piece is folded up at a diagnal to the top left to form the pocket.
The bottom right is folded at a mountain fold to bend closed.
Then you close it shut and glue each back to each other inward by an inch or so.
(this is so the flexibility of the open book can sort of allow the cover to move inward.)
The cover was like 6.5'ish chipboard covered.
Glue your ribbon on the inside cover and back cover before you adhere it to the closed pages.
