I am going to attempt to make some cowboy boots out of gumpaste. My only experience with gumpaste has been making flowers. To "glue" those together I used lemon extract. Will that be strong enough for the boots? I am reading that I can dissolve small bits of gumpaste in water and use it as glue. What is my best bet? These won't be eaten, but possibly kept as a keepsake. Do I need to hit the cake supply store, or can I use some items I have at home?

Here's two:

Nicholas Lodge's Recipe for Edible Glue
1. Bring one cup of tap water to a rolling boil and remove from the heat.
2. Add 1/2 heaped teaspoon of Tylose powder to the water. Stir well with a fork to break up the Tylose. Allow to cool, stirring often to dissolve.
3. If necessary, place the mixture in the refrigerator overnight to allow the Tylose to dissolve.
4. Place in an airtight bottle when cool. Has a shelf life of approximately 30 to 60 days, but will keep longer if kept refrigerated when not in use.
