Scrapbook Pockets

I am learning to how to do pockets from Clare Charvill, i am not good with numbers, so that that means measuring, so how she explained and how i am getting what she says are too driffant things, but i am trying and i did finely get it so i do have one template on a small type of pocket, it would be very easy for someone else to get it but for me i have to keep watching and listen over and over to finely get what the person is saying, so i have to keep watching Clare and listen to her and i will finely understand what she is saying about the pockets.
