How to Join in the Round on Circular Needles

Joining in the Round on Circular Needles

Circular Needle Length
Before joining in the round on circular needles, it is important to make sure you have the right length of circular needle. Aside from the actual diameter of your needles (ex: US size 9), a circular needle has a length (ex: 32"). You'll want to make sure the length is appropriate for the number of stitches you cast on and plan to knit.
After casting on your stitches, if they are spaced too far apart, you won't be able to spread the stitches all the way around and it will make knitting difficult if not impossible. Conversely, if you have too many stitches for your circular needle, stitches may try to jump off the edges, and it will be difficult to navigate a pattern.

Twisted Stitches
Next you'll want to make sure that your stitches are not twisted before you perform a join. The easiest way is to start at one end and align the cast on spine towards the center of the circle formed by your needles. Ensure that the stitches are not winding around the circular needle anywhere along the cast on or else you'll end up with a mobius piece!

Circular Needles

Circular needles are like straight needles that have a small plastic wire connecting the ends so you can knit continuously without turning the work as in rows.
The dynamics of certain stitches changes when you switch from knitting in rows to knitting in the round, because you are always knitting on the right side (RS) of the work.
