Sprinkle the gelatin into the cold water to soften. Pour into the boiling water, stirring until dissolved. Add the remaining ingredients and mix well.
To use glue, brush thinly onto the back of a stamp or some paper and let dry. When applying to paper, just moisten it a bit. To keep, store in a small jar or bottle with a lid. Warm in a pan to turn into a liquid again.
