Don't know if anyone else does this, but when I have a paper piecing template that I need multiple copies of, I use newsprint size to fit the printer and just run copies. Bet you could also cut foundation sheets or some interfacing to size and run it through also. Sure saves me a lot of time. You can buy newsprint (a really thin paper) for your printer at amazon pretty inexpensively. freezer paper also runs through the printer.
Just wanted to share some of my shortcuts and money saving and time saving ideas.
Have a wonderful day, week, month, holiday and New Year.
