Considering how complicated this card looks when it's completed, I was actually surprised (and pleased) by how simple it really is. It's actually two card blanks, cut on an angle, and joined together by a couple of slits. It folds flat for easy postage and can easily be made in different sizes depending on your envelope.
1. Start with two card blanks measuring 6" tall x 8" long.
2. Lay each piece horizontally (landscape) on your score board and score at 4", which will be the centre fold.
3. Now cut a diagonal section from the top of each piece of cardstock, starting at one of the top corners. It doesn't matter how steep your angle or how much you cut off as long as it's the same amount on both pieces of cardstock. On one sheet, begin the cut from the top left corner, and on the other sheet begin the cut from the top right corner. (For interest sake, my cut goes from the top corner to 3" down the side.)
4. This next part is a little bit tricky... 2" from either end, rule a vertical line down each piece of card then measure and mark the centre of each of those lines. I found the easiest way to do this was to use a centering ruler and pencil.
5. Use a craft knife and ruler to cut from the centre mark down to the BOTTOM on ONE piece of card. Then cut from the centre mark up to the TOP on the other piece of card. These are the slits that will join the card together. Erase the lines.
6. Fold along the score lines you made in step 2... then have a quick go at slotting the two pieces together. You may need to adjust your cuts if the two pieces don't line up properly.
7. Use co-ordinating papers to decorate the front and inside of the card pieces. Don't forget to cut the slits back in once you have added the patterned paper.
8. Add some pretty punched borders, again remembering to cut the slits where necessary.
9. Fit the pieces back together and then add another strip of punched cardstock along the bottom. This will help support the card since it goes over both pieces of cardstock.
10. Make a tag measuring 33/4" wide x 41/2" tall and add a punched strip along the top. This will slide nicely inside the card and is perfect for a sentiment and a message to your recipient.
11. Now decorate your card as desired. Have fun!
