For Ginger....
it is easy to see which side is waxed....it is shiny and the other side is not
you iron the waxy side to whatever you want it to stick to.
dry iron - med/high setting is what i use
nothing will will happen if you iron on the wrong side....it is just waxed paper
NO printer for me --- any printer that heats the paper will make a mess because the heated freezer paper will stick. HOWEVER.... i have ironed fabric to the freezer paper in an 8 1/2 x 11 size to then run through my printer so that i could print a picture i wanted to embroider on the fabric. I think you can put it through printers that don't heat the paper.
