On plain paper draw some very faint pencil lines with a ruler to act as a guide.
Use Berol Colour Italic Lettering Pens to mark out the writing you have chosen - make the very first letter really beautiful. You could make the first letter bigger than all the others, or do it in a different colour.
Or you could decorate that first letter. This is called illuminated lettering. It was used centuries ago before books were written by hand instead of printed. A very special book, like the bible, would be hand lettered by monks and the letters were illuminated with different colours and with real gold.
