STEP-BY-STEP PICK UP AND KNIT
Holding the piece of knitting you are going to pick the sts up from in your left hand, and starting at the top-right corner, insert the right-hand needle between the first two stitches of the row. Wind your yarn around the needle and ‘knit’ the first stitch... ...And pull the new stitch through between the two stitches.
Continue to work like this along the row or until you have picked up the necessary number of stitches. Try to space your stitches evenly.
