I put just a spritz of basting spray on the template. It sticks to the fabric and pulls away easily. I must admit, I don't let the project sit, I only do it if I can cut and peel right away. I don't know if time would make the paper stick too well to be peeled back.
The other thing is use freezer paper with the shiny side down and press it onto the fabric. You can buy freezer paper cut into 8 1/2 x 11 pieces so they feed through the printer.
