My own D.I.Y. mini sketch pad/book

I made this cuz I have no money and the sketch pad/books are to big in my bag and even the small ones are only 10-20 pages which it cost like ₱35 and the big ones are ₱50 above. So I made my own using
Half of the Long band paper, color paper, and folder. And of course how can I cut it without scissors. And pokemon stickers
