Abstract: The needle-threading device is configured for use with a plurality of weave configured for use in sewing a hair weave. The needle-threading device: a) stores the plurality of weave needles; b) automatically threads each individual weave needle with a yarn; and, c) individually dispenses each threaded individual weave needle. The needle-threading device comprises a yarn feed, a threading mechanism, a needle mechanism, a housing, and a control circuit. The housing contains the yarn feed, the threading mechanism, the needle mechanism, and the control circuit. The control circuit controls the operation of the yarn feed, the threading mechanism, and the needle mechanism. The yarn feed provisions the yarn required to thread each individual weave needle. The threading mechanism threads the yarn through the individual weave needle. The needle mechanism transports each individual weave needle as required through the hair weaving process.
