Moss Stitch is the pattern stitch that is used in the Ombre Fun Blanket, and part of the building blocks of your knitting skills. Once you have mastered to cast on, knit garter stitch (knit all stitches), and cast off, this should be the next stitch to master. Knit 1, purl 1 can be used in this way but is also the same stitch pattern used for ribbing (but in a different sequence).
Here is the video, but if you’re struggling with it, or need any clarification, do not hesitate to let us know. Happy knitting!
