flavouring and and sugar. Stir to dissolve gelatin. If the

gelatin doesn't dissolve, put into microwave again for 10 second

intervals until gelatin is dissolved and liquid.

glue in a very thin layer on the flap of your envelope. When

completely dry, moisten as usual and press flap closed to seal

refrigerator for up to 2 weeks. To re-use the glue, heat in the

microwave on low in 15 second intervals until liquid again.
