Now at the halfway point, I think it's turning out well and I'd consider doing another scarf this way. Instead of casting on the width of the scarf and knitting to the desired length, you cast on the length of the scarf on circular needles and then knit the other way. This way I can knit vertical stripes, which are pretty cool too!
I finished the scarf in less time than expected. It turns out the pattern is for a 10" wide scarf and I'm not crazy about wide scarves and so I edited the pattern which was supposed to a repeat of the red, yellow, green, and blue and then red once more with white between each stripe. It started out as a Hudson Bay blanket inspired scarf, but I really do think it is more of a Fruit Stripes bubble gum scarf.... This one was fun and I have lots of yarn leftover. I might have to make another one!
