Here is a quick run down of how to make wheat paste in under 10 steps. This wheat paste recipe has worked for me, however there are usually a multitude of variations to complete any task.

1. Fill a standard bowl (such as a cereal bowl) with cold water.
2. Add 3 tablespoons of wheat (or white) flour to the cold water bowl and mix thoroughly with a fork. Break apart any lumps of flour that get clumped together while mixing.
3. Boil one cup of water in a covered cooking pot.
4. Slowly pour and stir your cold water flour mixture into your boiling pot of water. At this point you should have a nice watery / wheaty mixture in your cooking pot. Keep cooking uncovered and bring to a boil.
5. BE SURE TO KEEP STIRRING
6. Your boiling mixture should begin to thicken after a few minutes.
7. After it has thickened, turn off the heat source and stir in 1 table spoon of sugar.
8. Remove from heat source and allow to air cool.

This is a rather simple process for creating a strong glue. Adding sugar is not entirely necessary and other types of flours may be used. You should be able to smear on this mixture like any other glue. You can store your left over paste in an airtight container in your refrigerator, however I have found that freshly made paste has a more workable consistency.
