Ok here we go i have taken pictures of both the designs i use 1 is a full front card other is a half front card. It's entirely up to you which one you use. I use both depending on the image and backing sheets i want to use .
You need A4 sheet of card
Score board or decent ruller and score tool
Backing Papers and Image
firstly take you A4 card and score on the A4 half fold line (or find the middle of the card) This is your A5 card blank
