When you pick your work up again, you said it ends up looking funny. Is there a hole, a big loose stitch, something else?
Your working yarn will always be with the right needle if you put it down in the middle of a row, that's good to remember; otherwise you can inadvertently turn and start going the wrong way. Are you maybe dropping a stitch? Twisting stitches?
You can check the free videos, link at the top of the page, to see if you can narrow things down a little.
And the one I've always liked least: Practice, practice, practice.
