I got the template for these flower cards from the internet, mirkwood designs I think.
The silver and pink one was my second attempt. I made a box for that one.
these are really versatile, just put whatever occasion in the centre of the flower.
As you can see on picture 4 I placed the flowers on a square card, folded so it springs up on a sort of stand. I guess there's a name for that card fold but I don't know what it is.
I guess you could make more layers for a really big card, just remember they have to be folded up, it seemed to take forever!
