I just wanted to share with you something I tried today.
Instead of using new printer paper to print out the foundations for paper piecing, I used the clean side of sheets that I had already printed on. Since we are tearing them up anyway, I didn't see the need to use a clean sheet.
I did test the ink by ironing and steaming a sheet, face down, on top of a scrap of light colored fabric to make sure that the ink didn't transfer, but so far, so good!
So....start saving anything you misprint or no longer need, and run it through the printer again and get a two-for!
