Weigh the Ingredients - Carefully weigh out the corn syrup and sugar using a kitchen scale. Measure out the tylose powder.
Combine Sugar and Tylose Powder - In a large bowl, use a sifter to combine the sugar and tylose powder. This will ensure that the ingredients thoroughly combine.
Add the Food Coloring to Your Corn Syrup - Add your choice of gel food coloring to the corn syrup. Use a spoon or whisk to thoroughly blend the two.
Combine the Sugar Mixture With the Corn Syrup Mixture - Mix all the ingredients together in a large bowl using a rubber spatula. Make sure all the color is evenly dispersed.
Add Sugar Paper to Silicone Mat - Lightly grease your silicone mat with cooking spray or a neutral-tasting oil. Add your separators, if desired, and begin rolling out the sugar paper.
Cut the Sugar Paper - Using a sharp knife or pizza cutter, cut the sugar paper into the shape you would like for your cake decorations. If desired, add any additional coloring or designs you want to the sheet.
Allow the Sheets to Dry - Allow the sheets to dry at room temperature overnight, or for 6-12 hours. Drying time will vary based on the humidity. The more humid your house, the longer it will take to dry.
Add the Sheets to Your Cake - Carefully add the sheets to your frosted cake. If you are having problems with the designs sticking, lightly mist the frosting. Frosting that is slightly wet will help the sheets stick better.
