Pan temp: The temperature of the pan can be measured by adding a small amount of water. The water should bubble, but not evaporate (this means it's too hot). The temperature of the pan is vital to how the crepes cook.

Crepe size: If the amount of batter you are using for each crepe doesn't coat most of the pan, slowly increase it.

Flipping: Run your spatula around the bottom edge of your crepe. If it cleanly separates from the pan, it is ready to flip.
