Mishnah Shabbat 15

¹These are the knots for which a person is liable? Camel-drivers’ knots and sailors’ knots. And just as one is guilty for tying them, so one is guilty for untying them. Rabbi Meir says: any knot which one can untie with one hand they are not liable for it. ²You have some knots for which one is not liable like [one is] for camel-drivers’ knots and sailors’ knots. A woman may tie up the opening of her chemise, the strings of her hair-net and of her belt, the laces of her shoes or sandals, leather-bottles of wine and oil, and a meat dish. Rabbi Elazar ben Ya’akov says: one may tie [a rope] in front of an animal, that it should not go out. One may tie a bucket [over a well] with a belt but not with a rope; Rabbi Judah permits it. Rabbi Judah stated a general rule: any knot that is not permanent one is not liable for it. ³One may fold clothing even four or five times, and spread the sheets on the beds on the Shabbat evening for [use on] Shabbat, but not on Shabbat for [use on] the day after Shabbat. Rabbi Yishmael says: one may fold clothing and spread the sheets on the beds on Yom Kippur for [use on] Shabbat, and the fat pieces of the Shabbat offering may be offered on Yom Kippur. Rabbi Akiva says: those of Shabbat may not be offered on Yom Kippur, nor may those of Yom Kippur be offered on Shabbat.
