be decoratively colored for example a sheet of gold leaf material could be used to provide a gold tint to the letters in order to insert the sheets into the looseleaf binder a selvage section 62 is formed along the inner edge of the sheet protectors the selvage section 62 is defined by means of the heat sealing indented channel 64 separating the pocket 52 from the selvage section 62 within the selvage section a plurality of holes 66 are formed with the peripheries of the holes being heat sealed together at 68 by means of the heat seal operation the hole effectively becomes reinforced so it can be securely retained within the binder rings in order to utilize the sheets for indexing the particular tab locations on successive sheets can be positioned in a sequential manner thus the tab bearing the letter a is placed at the top of the sheets and the next tab bearing the letter b is placed at a location spaced in sequence from the tab bearing the letter a similarly the other tabs can be positioned so as to be spaced adjacent to each other so as to permit easy identification of the indicia formed thereon at the opposing ends of the selvage the sheet itself is shown to include upper and lower shoulder portions 70 so as to permit easy access to the releasing levers 26 28 the complete periphery of the selvage section.
