Must be steam set using the stovetop steaming method.
This is the most unique of our water based resists. Because it is made by Silkpaint!, it holds the line pretty well for the Serti Technique. Unlike other colored water based resists, which behave more like a paint, this acts like a clear resist with dye in it. When you steam it, you set the dye in the resist as well as the dye of your painting. When you wash it, you wash out the resist and leave the dye. Therefore, it leaves no feel on the fabric, just like a clear resist that has been removed. The color of the line ends up more like charcoal, depending on steaming time and other factors. If you want a deep black line, you will need one of the other black resists that stay on the fabric like a paint.
