@share_sun @fesshole a shoelace is a double-slipped reef/square knot. The first half is the same as a usual reef knot (one lace crossed over then under the other).
For a reef knot, you want to then cross the rope that was on top of the crossed rope in the first half be the top rope again, but it is now on the other side. So if you went right rope crossed over left rope (and then under), for the second half you cross what is now the left rope over what is now the right rope (and under, although in the second half it is just under the new cross and not the original cross)
For a shoelace, this wants to be double slipped so you can untie it easier. So for the lace underneath, you make a loop instead of just using straight rope. For bunny ears, you make 2 loops and complete the knot. Otherwise you make the loop for the lace underneath, then pass the top lace over, and passing it through the loop halfway along the lace instead of the end.
