Definition:
The fold lines in paper with parallel folds all run in the same direction, parallel to each other. Parallel folds are commonly used for all kinds of brochures (such as tri-fold), stationery inserted into business envelopes, and other materials. The specific direction of each of the parallel folds determines the type of folding pattern.
Crossfolds might be considered the opposite of parallel folds because the fold lines cross each other.
Examples:
Accordian or Zig Zag, Spiral and C Folds, and Gatefold all incorporate two or more parallel folds.
