How to Stiffen Fabric With Sugar
- 1). Finish the cloth project you are making and determine if it can be safely placed in water without damaging the fibers of the fabric.
- 2). Use a clean pot that is made from glass or has an enamel coating on the inside. Make sure that there is nothing adhering to the pot or it might transfer oil or other substances on to your finished piece.
- 3). Add 2 cups of cold tap water to the pot. Measure 2 cups of sugar and add to the water. Stir well and bring the liquid to a boil. Remove the pot from the stove.
- 4). Let the water cool until you can touch it without getting burned. Immerse the finished piece into the sugar-water mixture and allow the liquid to soak through the fabric for about 15 minutes.
- 5). Place the fabric on a mold that is the same shape as the desired shape of your objective. For example, if you want the object to dry flat, put it on a flat surface, making sure there are no wrinkles in the material. Let dry at least 24 hours.
