❓1. What size baking pan is used?
The baking pan used is 28x28.
❓2. Should I use oilcloth or parchment paper? How to make oilcloth transparent?
It is recommended to use oilcloth, as parchment paper may wrinkle and is not as suitable for creating a smooth surface. If your oilcloth is not very transparent, you can lightly grease the surface with oil, similar to how paper becomes transparent when soaked in oil.
❓3. How to use digital templates?
After saving the digital template, print it on A4 paper with a printer. Place the template under the baking oilcloth. Print the pattern to fit your baking pan, for example, mine is 28x28, so the pattern is about 26.
❓4. Do I need to bake the hand-painted batter before using it?
After creating the hand-painted pattern, refrigerate it until ready to use.
❓5. When should I remove the oilcloth?
It's generally best to remove the oilcloth while it's still hot to keep the pattern intact.
