Reference for Shabbat 13:2

הָעוֹשֶׂה שְׁנֵי בָתֵּי נִירִין בַּנִּירִין, בַּקֵּרוֹס, בַּנָּפָה, בַּכְּבָרָה וּבַסַּל, חַיָּב. וְהַתּוֹפֵר שְׁתֵּי תְפִירוֹת, וְהַקּוֹרֵעַ עַל מְנָת לִתְפֹּר שְׁתֵּי תְפִירוֹת:

If one places two threads of the warp on the cross-beam on the nirin [The gemara explains that he affixes twice every strand of the warp on the cross-beam, and the third time, he affixes it to the strand on the shaft], or on a keiros [a sheet woven of palm bast], a sifter, a sieve, or a basket, he is liable. And one who sews two stitches, and one who tears in order to sew two stitches [is liable].
