I scarves are fairly quick and easy projects, great for gift giving! Use a single color, use a cake yarn and let the color flow as it wishes, or use it as a scrap buster which I did on one of mine!

US terminology

Stitches you need to know
Foundation half double crochet
Double crochet
Optional standing double crochet
Single crochet
Half double crochet
Chain

This is a simple two row repeat.
On my scrap buster color block version, I Just did 6 rows of each color unless I was running out of my yarn. Each time you make one of these, it will look different and unique! Have fun!
