Hi Bluebird,
The Prym Dritz website says don't use Printed Treasures with laser printers or commercial copiers. You have to use them with ink jet printers. If you don't have an ink jet printer, I would try another way to make the quilt label.
Many of the quilters in my guild make quilt labels by hand using Micron Pigma pens. They have waterproof, fade-resistant archival ink.
I hope this helps.
Happy quilting,
Judith
