# 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). Kitzur S"A 80:45 and Yalkut Yosef (317:11) agree. </ref> For example: a ribbon on a gift, a single bind on a shopping bag or garbage liner.
# It is permitted to tie a slip knot or bow without a underlying knot even if it is tight and meant never to be undone. <Ref>Shulchan Aruch (317:5), Biur Halacha 317:5, Yalkut Yosef (317:11, [[Shabbat]], vol 2, pg 562), The Shabbos Home (Rabbi Simcha Cohen, vol 1, chap 13, pg 207) </ref>
# After tying a bow knot (a bow on top of a single knot), as is common when tying one's shoes, one may not tie a second bow on top of the bow knot. <ref>39 Melachos (Rabbi Ribiat, vol 3, pg 798) </ref>
