Attach the film to the drawing board with two thumb tacks, using a tee square to insure the perpendicular lines on the negative being parallel to the sides of the board. To facilitate this adjustment a piece of white paper may be placed beneath the negative. If passe partout binding is used, cut two pieces from the roll, one the length and the other the breadth of the negative. Each of these strips may be divided down the middle. Moisten the four strips, take one, and with the tee square as a guide affix it in position on the negative. Go around the other three sides in the same manner, moving the thumb tacks if necessary. One thing to remember is that there should not be less than two tacks in the film at the same time, which will prevent displacement. This arrangement is shown at Fig. 1, in which c d e f is the negative, and the shaded portions two strips already affixed. When the strips are affixed on the four sides, remove the thumb tacks, lay the negative on a smooth surface, film side down, and with a piece of soft rag press the back side of the negative to insure perfect adhesion of the strip. Place the negative under pressure until dry, when it may be trimmed with scissors, if any part of the film extends beyond the masking strips, and is now ready for printing from.

The white margin on the print can be trimmed to the desired width.

If ordinary black paper be used instead of passe par-tout, it may be cut into strips in the following manner:

Take a piece of paper about one inch wider than the length of the negative. Fasten this to the drawing board with thumb tacks, at the same time fastening the tee square, as shown at Fig. 2. With a set square as a cutting guide cut the paper into strips about a

quarter of an inch wide. By moving the set square in the direction indicated by the arrow, the strips may be readily cut off. It is advantageous in cutting these strips not to sever them completely, except every four. They can then be pasted in batches of four, which takes less time than pasting them separately.

There are certain photographs on which a dark-colored border is more suitable than a white one. With film negatives this is very easily obtained. Trim the negative to the size required, and print with the printing paper extending one-quarter of an inch all around. The dark border so obtained can be trimmed to the desired width.

For those who like novelty a double border may be made on prints. The film is masked as described above and the mask and film trimmed, leaving only a narrow margin masked. A print from a negative so trimmed, with the paper so extending beyond the negative, will have a white margin next to the print, and outside of of that a dark one, which can be trimmed as desired.
