This is not exactly a pattern, but more of a technique that I want to share so you can make one of these beautiful crocheted scarves. It's such a great way to use handspun yarn or yarn leftover from other projects.To start, chain until you reach the desired length of your finished scarf (without fringe). Turn and single crochet all the way back. The first row is especially difficult, since you don't have a lot of leverage to get your crochet hook into the stitches. Don't give up! It gets easier, and it's worth it.
Continue singe crochet, back and forth, switching to new yarns whenever you want to. When you add or drop yarns, leave a tail about the length you want your fringe to be, and they can be worked right into the fringe when you're done. The weight of your yarns should all be similar, but you can also work two yarns at once to make thin yarns more bulky. Use very similar yarns for the beginning and end rows, so that they will even out any inconsistencies caused by the different yarns.
These scarves initially tend to curl into sort of a spiral. This can be fixed by blocking and by wearing it a few times. That's all there is to it! Enjoy your new stripey scarf!
