the pattern I am following consists of pearls and knits. I realised that at the beginning of the patten I missed a knit so when I have gone back to unpick it I have been faced with this and not sure what to do to correct it. I have attached pictures of what it looks like from the back and the front.

Welcome to the forum!

The pattern looks very nice. You could slip the stitch with the blue dot off the needle and pick up the stitch below it marked with the red dot. With the red dot stitch on the left needle in this photo
pick up the 2strands circled in orange with the tip of the left needle and lift the red dot stitch over them and off the needle. That should give you a knit stitch as seen from this side.

Thank you so much for your help!!!
