Lay the temple upside down on the warp, up close to the reed, and remove the metal pin. Slide the temple open to lengthen it just enough that the middle of the teeth line up with the edge warp thread at the reed. Take a peek and see where the closest holes line up for the metal pin. Shorten the length a little if necessary to line up the holes and insert the pin. Place the teeth in the weaving 1/8-1/4" away from the selvedge and 1/4-1/2" away from the last weft. Be sure the metal pin is away from the reed. Weave about one temple's width and then move the temple forward on the weave. Move it more frequently with very fine and tight weaves. It is best to weave a little bit after moving the temple before advancing the warp on the loom in order to avoid weft streaks.
