the device provides for the formation of a cd jacket using conventional or custom dimensioned paper by imparting a diagonal folding pattern to the paper to be used for the cd jacket . the folding pattern is imparted to the paper and a defined series of folding steps followed to yield the cd jacket . reversing the last step in the folding sequence provides access to the internal pocket formed by folding the paper through an aperture in a top flap . completing the last step in the sequence seals the internal pocket . the folding sequence may be imparted to the paper using printing or scoring or both to yield the diagonal lines on which folds are made .
