ENVELOPE GLUE RECIPE

Ingredients:
6 tablespoons white vinegar
4 - 1 oz. packets unflavored gelatin
1 tablespoon vanilla extract (or any flavor that you like)

Bring vinegar to a boil in a small pan. Add gelatin and stir until dissolved. Add extract and stir until mixed. Brush on thin layer onto back of an envelope flap. Let dry. Moisten to apply.

Store excess glue in a sealed container and melt again for future use by putting in a pan of warm water.
