How to: The Magic Loop
This fabulous technique allows you to create a small tube, such as a sock, on one circular needle!
Divide your stitches in half. Fold the cable so that half of the stitches are on one side and half on the other.
Pull on the bit of the cable that appears between the two groups of stitches.
Slide the two groups of stitches down to their respective needle tips. With the needle tips parallel and pointing to the right, your working yarn will hang from the back stitches.
Pull on the needle tip that is holding the back stitches, and draw up enough slack on the cable to allow you to use the needle tip to work the stitches on the front needle.
Join and work all of the stitches on the front needle.
Slide the two groups of stitches back down to their respective needle tips. Repeat as many times as needed.
