How do you stop loose stitches at the ends/beginning of your project? I can’t get the video “demo small project” to play. It will start then stop after long tail cast on. I tried to use, save target as, still no luck . I’m new to the knitting world and trying to make the elongated stitch scarf, but the elongated stitches are angling to one side. And you can see this BIG old loose stitch at the start of the knit row, after the elongated row…HELP!
