Has anyone used.....

Kiln shelf paper?
I got it todayfor the 2 rain chains that are glazed and ready to be fired. I bought the shelf paper so I can lay the chains directly on the paper and not mess the kiln shelf. My question is this. The paper came in a roll. NO directions. Does it matter which side is used?

I started another squiggle piece. Instead of making the lid normally I am draping the sides over the box.. and I May have gone a little nuts making squiggles. just hope that lid doesn't sag with all the squiggles!
