those skilled in the art in light of the foregoing disclosure merely by way of example the letter sheet 7 may be a multiple layer snap set with or without carbon paper the positioning of the envelopes and letter sheets on each panel may be varied considerably for example the upper edge of the envelope 5 could be positioned about 2 34 below an infold 35a and the letter sheet 7 could then be positioned about 51 2 34 below the infold 35a so long as the total length of succeeding panels 33a and 33b is less than the length of an overlapped envelope and letter sheet the dimensions of the envelopes letter sheets and carrier sheet panels may be substantially varied as may the amount of overlap between documents if desired each of the panels 33a and 35b may be folded in half to form an extra short form carrier system as shown in fig4 it will be seen that all of the original folds 35 thus become infolds 135a each envelope 105 is then affixed immediately below an infold 135a and each letter sheet 107 is affixed immediately above the succeeding outfold 135b on the 34 semi panel 34 133a three succeeding semi panels 133b 133c and 133d.
