is the pattern from Raverlry. There are three things I can suggest. One is to do several repeats of the pattern rows. I tried it and it didn't look like much until I'd finished about 16 rows. The second is to make sure you have an even number of stitches. And the third is to knit this pattern in a quiet place where you can maintain the mantra "p1, slip 1".
You can test it out on 10sts if you do it like the swatch that is shown in the video for swatching in the round.
