This part is going to be difficult to explain. Basically we are fan-folding the pages back and forth. There will be folds or valleys in the card holder. Every other side will have a fold along the inside edge. I hope I explained that well enough. Each page measures about 4 and 1/4 inches, except for the front and back pages which measures 4 and 3/4 inches. The reason they are wider is because of the bulk of the inside pages. You may need to fold it a few times to get the front and back pages to look even with the other pages. Press the pages to get a nice hard crease.The back flap folds toward the front flap and the front flap will fold over the back flap.
When you open the card holder, the back page flips out towards the right.
If anyone has any suggestions on how to re-word this part please do leave a comment.
