I was reading an article about paperless paper piecing and came across this:
"**A note about freezer paper: If you use Reynolds, or another brand found at a grocery store, it will need to be preshrunk. When ironed, freezer paper shrinks in width (about 1/8"), but not length. Preshrinking it will prevent inaccuracies as you reuse the template. To preshrink your freezer paper, tear off your desired length, lay it shiny side down onto your pressing board. Lightly spray it with spray starch, and press it with a dry (NO steam) iron until it is completely flat and dry. Repeat for your second piece of freezer paper. You'll notice it pulling in on the width. Once it's dry and flat, it's ready to be used. If you order freezer paper from my mom, it doesn't need to be preshrunk."
Here is the article in its entirety:
