Help! Picking up for border

hi everyone…im at the end of my yarn with this one! Knitting a cardigan for my baby girl and I’m about to start the border. The pattern asks me to pick up and knit 12 stitches from 9 cast on stitches.

I’ve searched google and I cant find an answer x

See if this video helps. Amy shows picking up in a stitch and between sts.

It’s also sometimes convenient to pick up a stitch in each cast on and then increase to the required number on the next row.

Thank you so much…that vid is a great help! Yey! X
