The acetate was too thick and didn’t fold properly and left a curve when it was pulled to the front. to resolve this if i score the acetate slightly it folds better. i have to be careful not to score it the whole way through though.
Below is a picture of the card. The original card shape is a big square. And i had to cut it down to an a4 size. As you can see below i cut it the wrong way and the fold didn’t work because its going the opposite way to the grain. i need to remember to cut the right size and have it running with the grain.
