Koshair (Tying) and Matir (untying)

== The Basics of Koshair ==

# The Melacha of Koshair is the binding two pliable items by intertwining them such as through a firm knot or twining threads into rope. <Ref> Mishna Brurah(317:34) quoting the Rambam, Shemirat Shabbat KeHilchata 51:52 </ref>  

# A knot that’s forbidden on a Torah level is one that is both (1) professional and (2) is meant to be permanent. <Ref> Shulchan Aruch (317:1) in the opinion of the Rambam and Rif </ref>  

# A knot that is a professional knot but isn't meant to be permanent or a permanent know which isn't professional is forbidden on a Rabbinic level. <Ref> Shulchan Aruch (317:1) according to the Rambam and Rif, Mishna Brurah (intro to 317) </ref> Some hold that a knot which is permanent even if it's not professional is Biblical prohibited. <Ref> The Rama (317:1) quoting the opinion of Rashi and Rosh  </ref>

# A knot that’s not profession and doesn't have any degree of permanence is permissible to tie. A loose knot which isn't meant to last more than 24 hours is permissible. <Ref> The Rama 317:1 quoting Tur and Mordechai; Mishna Brurah (317:6) explains it as anything less than 24 hours. </ref>  Some authorities permit even up to 7 days. <Ref> Rama also quotes Kol Bo and Hagot Maymoniyot. Yalkut Yosef (317:6) writes that Sephardim hold like this opinion. </ref>  

# Even if you personally intend to leave it less than 24 hours, if it’s a knot sometimes left permanently by people it’s forbidden Rabbinically to prevent confusion between temporary and permanent knots. <Ref> Magan Avraham (317:20), Kol Sinai (Koshair #3) </ref>
