Preheat the oven to 250F.

Line a cookie sheet with parchment paper and place pre-cut fabric (I usually cut mine in various sizes such as 8" x 8" and 12" x 12") on the parchment. 

Sprinkle the fabric with a a couple tablespoons of beeswax (a little goes a long way so you don’t need a lot).

Place the pan in the oven and check after 4 - 5 minutes to see if the wax has melted.

When the beeswax is just melted, remove from oven. Spread wax with a paintbrush to remove excess and coat any bare spots.
