Help on sock pattern

Ok…so im really new to knitting, and im going to now attempt at knitting a pair of simple socks…but i dont understand one part of the pattern…after ribbing the 7 inches…and binding off the stitches needed to be…it says cut the yarn. Ok…now the part i dont understand is…you now re-attached the yarn…so heres the question, why am i doing this lol…and how do you do it…would it not add an extra stitch on like it would as if joining yarn or a different colour? HELPPP!!!

thanks!

You’re knitting these flat right? If that’s the case, when you bind off the last 12 stitches your yarn won’t be in the right place to knit on the 24 stitches that remain, which is why you have to cut and re-join the yarn. I hope that helps.

You have 48 stitches. You knit the cuff and then it says:

Bind off 12 stitches, knit 24 stitches, bind off remaining 12 stitches and cut the yarn.

Abby is right the yarn is not in the right place and that is why you cut the yarn. You have 48, bind off 12 of them, knit the next 24 and then bind off the last 12. Count when you begin the last bind off of 12 stitches and make sure you are ending up with 24 in the part that will be left on the needle between the 12 bound off on each end. It is easy to make a mistake here sometimes.

Then you cut the yarn. Then take the yarn and go back to the 24 stitches left on the needle and just begin knitting with the ball again at that point. It doesn’t add any stitches. Just insert your right needle to knit and use the new ball end as your working yarn, and wrap and knit the first stitch and then just keep going across the row. You had 24, and you just knit across them without changing the number.
