This is just a picture showing some scor-tape on various edges of the cut and folded piece of 12"x9" designer paper.
DO NOT USE SCOR-TAPE - it's just for demonstration purposes. Use a wet glue as the inserted tags will catch on the scor-tape, that's why you should use the wet glue.
This layout just shows where you place the wet glue (on the INSIDE) without having to check each time. It just makes it easier to have a guide.
