Envelope mucilage is the glue used to seal envelopes. The mucilage goes on the flap, where it dries. Later, lick or moisten it to close the envelope. This glue is fun to mix and makes your homemade envelopes look polished and professional. This recipe makes about 1/2 cup of envelope mucilage, enough to cover several dozen envelopes. The lemon extract is just for flavoring; substitute vanilla or peppermint if you prefer.
Bring the vinegar to a boil in a small pan. As soon as it starts to boil, turn the heat to low.
2
Add the 4 packets of unflavored gelatin to the boiling hot vinegar and stir until the gelatin is dissolved.
3
Remove the pan from the heat and add the lemon extract. Stir until the extract is well mixed.
4
Apply the mucilage to the flap of the envelope with a small paintbrush, makeup brush or cotton swab.
5
Set the envelopes aside to dry. When you want to use the envelope, just lick the glue on the flap and seal.
6
Store leftover envelope mucilage in a small glass jar, such as a baby food jar. It keeps for several months without spoiling but thickens as it cools. To use it again, put the closed jar in a bowl of warm water to gently melt the mucilage. Do not add water to the mucilage.
