Gatefold Card Made From an Envelope Template

I was having another go with the Kizzy Dizzy cards this morning and it occured to me how easy it would be to make a gatefold card from the front of an envelope that has the flap attached. You'll need a Christmas envelope template though.
Print out 2 images like this one then turn it over and print a coordinating backing sheet on the back of the card.Cut out and stick one on top of the other so that the flaps become the gatefolds.
Crop the square and make it slightly smaller than the card for the insert (add a verse if you like)
Then a topper for the middle of the flaps.I also made the actual envelope. Again slightly larger than normal to house the card.
