How to fold a DL size leaflet properly!

Gary took a bit of time out to show me how to produce mock ups to a professional level. I know this is a bit geeky but it is definitely going to help me in future.

1. Print out two seperate sides of the leaflet
2. Score the central croplines using the back of the scalpal
3. Cut off the edges in an 'L' shape on the opposite side of each leaflet
4. Cut roughly around the edge of the uncut page
5. Stick together the edges and press down firmly
6. Fold the leaflet together and cut off excess bleed marks
7. PERFECT! Nice folded leaflet
