ABSTRACT:
A method of forming a double pocket envelope from a single sheet including the steps of cutting the single sheet to provide a base portion, a partition flap, and a front flap, and opposed end flaps; folding the partition flap against the base and folding the front flap against the partition flap, followed by folding the end flaps over the folded front and partition flaps; and cementing the end flaps. Next, the folded edge of the base portion and partition flaps are cut to provide a primary envelope between the base portion and the partition flap and a secondary envelope between the partition flap and front flap.
