How to make a sketchbook | tutorial sketchbook pro

Here is what you need to make a sketchbook:A cutting mat, a cutting liner, a cutting tool, a scoring tool, a pencil and eraser, paper, cardboard, book screws and a hole puncher.I wanted a sketchbook in the size of a square of 15cm by 15cm or 5,91" by 5,91" so I could scribble my wall art ideas in there.I cut my paper larger because I will make folds in them: 15cm by 19cm or 5,91" by 7,48"
