Crafter's Best Kiln Shelf Paper is made in easy to use convenient sizes, using the popular ThinFire Kiln Shelf Paper. It doesn't shrink in the kiln and features a printed pattern logo on the bottom side. The logo pattern does not affect glass or kiln shelves. Nor does it change the way ThinFire works in any way. But it does provide a benefit, the pattern makes it easy to recall how ThinFire should be positioned in the kiln. Just remember, logo side down against the shelf; plain side up, against the glass. Crafter's Best Kiln Shelf Paper is produced using 100 percent genuine Bullseye ThinFire Kiln Shelf Paper.
