Step 1 Lay hands palm down. Grabs each lace in each hand. Make two thumbs up. ( laces should oriented shoe-thumb side, aglet-pinky side.) Extend index fingers.

Step 2a With right hand loop the lace around your thumb then index finger. With left hand loop around the opposite way, finger then thumb.

Step 3 Place left hand index finger under right hand lace(between right hand index and thumb.)

Step 4 (simultaneous) Use right hand to grab left hand lace (around left hand index finger). Use left hand to grab right hand lace ( around right hand thumb)

Step 5a pull laces all the way through each other.

You now have the over under part.

Repeat steps 1-5 with these changes

Step 2b right hand - finger then thumb Left hand - thumb then finger.

Step 5b Do not pull laces all the way through.

You now have a finished knot.

If you ignore 2b And do 2a both times you will still have a knot but it is likely to come untied.

If you ignore 5b you will have a knot but no “bows”

Hope that helps!

Edit 2: A Ted talk on the process

Edit 3 Oops that ted talk only tasks about the normal way, this one does the fancy way that I was referring to.
