So here is my take on the challenge.
As most of the royal family served in the armed forces I thought I would base my card around that. Its also fits in perfectly for my Dad's birthday as he served in the Royal Navy.
I found this old page from a seaman ship manual containing signal flags so I used that for the main topper of my card. I have also used backing papers from Prima Natures Garden and the stamped images are also from the Prima Printery collection.
