I made this style card for the first time this week and I'm sure it's one Debbi came up with a while ago, so credit goes to Debbi Moore.
Here's what you need
3 pieces of card - 1piece measuring 5x5 and 2 pieces measuring 5x4
1 piece of acetate measuring 5x5
a topper and embellies of your choice.
Sorry forgot to add the acetate to the pic.
Score the 2 smaller pieces of card at 1, 2 and 3 inch mark and fold as in the picture.
Add your choice of backing paper to the larger piece of card and attach the folded pieces to the sides, at the back, with double sided tape.
Add your choice of topper to the centre piece and decorate the front pieces of the folded sides (this is the part you will see from the front of the card)
Put some double sided tape down each long side of the acetate.
Now attach the acetate to the folded card sides to the inside of the front fold. Add your sentiment to the bottom of the acetate, on the front side. Add anymore embellies and your done.
