How To: Endless Tail Cast On

This is a variation on the long tail cast on: it uses exactly the same technique, but instead of estimating the length of tail we will need, we use both ends of the ball to create an "endless" tail. This is helpful when you are A) asked to cast on more than 100 stitches, B) too fed up with estimating your tail, or C) working with two colors in one project and want to get creative with your edge.

Written instructions

Prepare your endless tail by taking both ends of your yarn ball. Decide which end will be your working yarn, and which will be your "tail".

Either make a slip knot with these two strands, or hold them in your dominant hand under the needle.


If you made a slip knot, place the slip knot on the needle. Ensure that your working yarn is to the back and your "tail" yarn is to the front.

Cast on the desired number of stitches. For details on how to perform this, visit the Long Tail Cast On page.

Once you have the stitches you need, cut or break the "tail" yarn. Yes, you have a few more ends to weave in at the end of the project, but you've saved yourself a lot of trouble with the cast on estimation.

Now, if you have a double-stranded slip knot, you have two options for dealing with it in the next round:

  1. Cast on 1 extra stitch, and when you reach your doubled slip knot, pull the slip knot out.

  2. Don't cast on 1 extra stitch, and when you reach your doubled slip knot, knit the two strands together as 1 stitch.

If you didn't use a slip knot, treat your first cast on stitch with care so it doesn't unravel as you work it.
