Arrange all your ingredients—shredded carrots, cucumber, herbs—in separate small bowls or on a platter for easy access.
Fill a large shallow dish or pie plate with warm water. Submerge one rice paper wrapper for about 10-15 seconds until it becomes pliable and translucent. Carefully lift it out using tongs or your fingers, letting excess water drip off.
Place the soaked rice paper flat on a clean, damp surface or plate. Layer a small handful of shredded carrots, cucumber, and herbs about 1 inch from the bottom edge of the wrapper.

Fold the bottom edge of the wrapper over the filling, then fold in the sides, and roll tightly to enclose the filling securely. The wrapper should be firm but flexible, with visible vibrant colors inside.
Repeat the soaking and filling process with remaining rice paper and vegetables. Arrange finished rolls on a serving plate lined with a damp towel to prevent sticking.
Serve the vegetable rice paper rolls immediately with dipping sauces like peanut sauce or soy sauce, or as is for a fresh, crunchy snack.
