WOW! I can't believe the response to this card! MAHALO ALL! I will try to do my best on this, as I have never done a tutorial before. Please have patience and send any questions you may have if I am not clear on the directions...
As I said, I saw a picture of this card and DID NOT have written info on the dimensions. Here is the BLURRY picture that I got it from:
I chose an envelope and made the card to it's size. Scoring your fold lines will really make it easier. Also, remember you can click on the picture to make it larger and easier to see. So here we go!
Envelope measures 6 1/4" x 4 1/4 "
The card base is 11 1/4" x 6"
Score and fold the base card piece in half (5 1/8")
On both sides of the center fold make two more folds 3/4" apart
At first fold line, fold the paper upwards toward you. At second fold, fold the paper away from you, third fold up, fourth fold away, and last one up creating the accordion in the middle! YEAH, the hard part is over!
The little panels that flop up measure 2 1/4" x 1 3/4" and you will need to cut 6 of them. Decorate them any way you like, the sky is the limit!
Attach the tabs as follows: On left side of first accordion pleat glue one at top and one at bottom 1/8" in from edge:
Next, on the right side of the first accordion pleat glue one in the center of the pleat so they are centered evenly.
Repeat this process again on the second pleat! Way to go, you've got it!
I sure hope this was not too confusing and that you are inspired to make a beautiful new kind of card! They are lots of fun with so may different possibilities, go for it!!!
