Explosion Box obsession

If you've spent any time on pinterest as of last, you will have seen a million of these "explosion boxes" come up. What makes this unique is that it folds into a regular 5 1/2 x 4 1/4 card!  So when the person receiving opens up the card, it "pops" open!
It's really fun.

I wanted to make one that was bright and cheery, so I choose to make this... with "sweets for the sweets" and as many bright colors as possible!

this is the back view: The white is so you can write on the "card".

Thanks for looking!
