One of the most important steps in using a pdf pattern is ensuring you print your pattern without scaling. If your pattern scales when it prints, your finished garment will not fit correctly.
Different programs have slightly different printer settings. If you see these options in your settings, here’s what you should do:
Actual Size should be selected
Scaling should be set to 100%
Fit to Page or Scale to Fit should be unselected
Orientation should be set to Auto or Portrait
