A slip knot is the foundation for many cast-on techniques. In fact, there are many ways to tie a slip knot. However, we are just showing our favorite method here.
You will find that many cast-on methods that start with a slip knot, also require you to leave a length of yarn free before you start tying the knot.
However, the length of yarn that you will need to leave free will vary. This will depend on the type of cast-on technique you are using.
One such popular cast-on technique is the Long Tail Cast On. You can find the tutorial for the cast-on here: Long Tail Cast On Tutorial.
If you have to leave extra yarn before tying the slip knot, we suggest you allow a length that is approx. 3 times the planned width of the cast-on edge.
Conversely, for other cast-on methods, we suggest that you leave an 8 to 10 inch (20 to 25 cm) yarn tail before you tie the knot.

Step-by-step Tutorial on Making a Slip Knot

First, begin by holding a piece of yarn on both ends. The short end, which is near the yarn’s tip and the long end, which is the side attached to the yarn ball.


Then, place the long end over the short end to create the first loop.


(A) Secure the first loop by holding on to where the yarn overlaps. While doing so, take a portion of the long end under the first loop and (B) pull it through and (C) up, creating a second loop.




Hold on to the second loop as you let go of the first loop. Then pull the short end, creating the knot.



Lastly, slip your knitting needle through the second loop and tighten it by pulling the long end.
