I just uploaded my most recent photo-diagrams: How to fold my Octagonal Envelope; a very easy and practical model for giving CDs for example

Anyway, I wanted your help for choosing my next photo-diagrams. I have three options:
Pedestal
Lid with 3D Triangles
Octagonal Case with Blossoming Seal
Sorry for the last image... I didn't have a better picture

So which photo-diagrams should I make next
