== A bow==
# A bow-knot, slipknot, or a single-knot isn’t a true Kesher-bind and is permissible even if it does remain in place for a while. <Ref> Shulchan Aruch (317:5) and implied by Rama (317:1), brought by the Yalkut Yosef (317:11) </ref> For example: a ribbon on a gift, a single bind on a shopping bag or garbage liner.
# An adjustable loop necktie that can be undone by pulling is permissible if one intends to take it out within 24 hours. Some permit even if the tie isn’t usually undone after wearing. <Ref> Shemirat Shabbat KeHilchata(15:58), Rabbi Reuven Feinstein in name of his father Rav Moshe Feinstein </ref>
== A bow on top of a single knot==
# According to Ashkenazim, it is permissible to tie one's shoelaces or a decorative ribbon on a blouse with a bow on top of a single knot (initial winding) only if it’s meant to be untied within 24 hours. <Ref> Shulchan Aruch (317:5) rules that a bow-knot isn’t a Kesher, on this the Rama adds that a bow on a single knot is permissible. The Mishna Brurah (317:29) qualifies this that it’s only where the single knot isn’t meant to last (more than 24 hours). Shemirat Shabbat KeHilchata 15:53 (in new edition 15:56) concurs. </ref> According to Sephardim it is permissible even if it isn't meant to be untied within 24 hours, yet it's preferable to make sure to untie it within 7 days. <ref> Yalkut Yosef(317:11), Az Nidabru 6:22, and Rav Ovadyah in Kol Sinai (Koshair #5) rule that some permit even if the single knot is meant to last but says it preferable to be stringent if the knot is meant to last 7 days. </ref>
