To make waxed cotton fabric, melt beeswax onto flat pieces of cotton fabric. Working with small pieces of fabric and melting the wax in the oven makes this project much easier.
In addition to the wax and cotton fabric, it's important to use the proper baking sheet in order to keep the oven as clean as possible.
Step 1: Prepare the cotton fabric
Spread the fabric on an edged baking sheet. Do not use a flat baking sheet or the wax can drip into the oven.
Step 2: Add the wax
Turn the oven on to preheat at about 150 degrees Fahrenheit. Scatter the beeswax shavings and crumbles on top of the fabric.
Step 3: Melt the wax
Melt the beeswax in the oven for about 10 minutes. Quickly brush any uncoated spots with a paintbrush to spread the melted wax.
Step 4: Remove the fabric
Quickly remove the fabric from the cookie sheet to avoid sticking.
