Measure out the shrimp mixture into the wontons and fold them up into little pockets. You can do traditional style wontons, but for these thai syle wontons, I like to fold them up with the top of the shrimp mixture exposed. To do this, place some of the mixture in the center and fold the sides up to form a square. Next bring in the corners to tightly wrap the mixture, still leaving the top open. This is a tricky maneuver, but it becomes easy after you do the first 5 or so.
