Start with a 12″ long piece of card stock that is 5 1/2″ tall. This size will fit into a standard invitation size envelope when all folded.
Score at 2″, 4″, 8″ and 10″
Turn the card stock and now measure 1 1/2″ in from the long side. Use your craft knife and make a slit starting at the 2″ score and bring it down to the 10″ score mark. Make sure to do this on BOTH long sides.
This picture shows the mountain & valley folds much easier than can be written out. Just take a look and make your folds as pictured.
Now I’ve added decorative scrapbook papers (DSP) to each of the surfaces of the card. I made sure to leave a little boarder around each piece of the DSP; 1 for looks and 2 so that when the card is folded the DSP won’t buckle.
Stamped and embellished. This view shows me looking down on the card so you can see all of the 3-d folds.
I’ve laid the card flat for photographing so you can see all the decorations.
I’ve got the card tipped a little bit for photographing, but this is the open view while standing.
Here’s how the card looks all folded up and ready to be inserted into an envelope.
