For a different take on a common stitch, why not try the criss cross double crochet stitch? This technique is sometimes called cross-over double crochet and it is exactly what it says on the tin. It is worked in sets of two stitches, with the first double crochet worked in the second stitch before you backtrack and work the second double crochet into the first stitch from behind. Here is an excellent tutorial. I would definitely suggest this stitch to a beginner because they will utilize skills they likely already have with a little twist to make it interesting. Also, the motions performed will help to prepare you for around the post crochet if you haven't tried it yet. I'm in a perpetual state of stash busting. This criss cross project was great because I made it for a tall girl and it used up a lot of yarn!
To finish I added a simple picot border. Fringe might have looked nice but the scarf was already so long that I didn't think it would be a good idea. This stitch has a nice rhythm and a modern look to it.
