Printing tips
Print the PDF that matches your paper (US Letter or A4) at 100% / actual size. The black-and-white chart pages save colored ink.
Pick the right paper size
Your download has the pattern in both US Letter and A4. Print the one that matches your paper and choose Actual size / 100% in the print dialog (not "fit to page") so the grid prints at its intended size.
Save ink
You don't need to print everything. Most stitchers print the thread key and either the color charts or the black-and-white symbol charts — not both. The black-and-white pages are easiest on ink and are just as clear.
Make it bigger
If the symbols feel small, print at 110–125% on larger paper, or use the full-size chart image on a tablet and zoom in.
