There are all patterns you can download and print.
But if you have no printer it`s not a problem! Just open masterclass.pdf and find there the second page. Then zoom it as you want and measure the bar with mark "29 cm". For example, on your monitor this bar is 15.5 cm long. Divide 29/15.5, you get 1.87. Now you can measure any object of the patterns and multiply this measure on 1.87 and the result is the real measure to draw on your paper for patterns.
