Finish it up, launder it, set it aside for a couple weeks then get it out, hang it or lay it on a bed and step back. Take another look. You may see it with truly fresh eyes. Up close we can all pick out every little ( self critical) mistake. Look at it from a few feet away and it is really quite ok most of the time. Once washed & dried you probably won't even notice those ( less than straight) lines.
