I'll place my 8.5-inch by 11-inch piece of light weight cardstock in the printer, and choose File > Print.
I now need to go back into the Layers panel and click on the eye icon for the stripe pattern to make it invisible, and click in the empty spaces where the other eye icons once were, so to view them again and to make the template lines reappear on the artboard. I'll then print the template on the opposite side of the cardstock.
Every printer is different, so before printing I want to be sure as to which way the paper should feed in, and if it should be face side up or face side down in order to print on the opposite side.
Once the basket_2 file has been printed on both sides, I will print the basket file in the same way.
