Frosted wavefold. Frosted is strong and versatile, with these qualities in mind wavefold folders were developed.
Most materials are folded using right angles, but by putting a wave in it instead, frosted becomes more rigid and eye catching too.
They can be used on one or more edges, and can be single, double or multiple. Single wave folds have the unique ability to make capacity with a single fold. Dual waves create a more conventional space while multiple waves can be used to make round spines.
