Print nonograms at 10x10, 15x15 or 20x20, one, two or four per page, with the finished pictures on the last page. Clues print large enough for a pencil, and every fifth line is thicker to help you count.

Printing tips
A pencil and a light X beat a pen on paper nonograms: you will cross out more cells than you fill.
Which size to print
A 10x10 picture is a coffee-break sheet and fits four to a page. A 15x15 wants two to a page so the clue numbers stay legible, and a 20x20 is best alone: its clues get long, and the pencil needs space. Every fifth line prints thicker for counting.
Using the answer key
The answer page shows each finished picture in grey with its name, so you can compare the shape at a glance without reading cells. If your picture looks wrong, recount the rows where your blocks disagree with the clue first.
