I finished alien #4 on the scarf today. The pattern only calls for 6, but I may go with 7 or 8, just depends on how much yarn I have. I reversed the pattern for every other alien.
Tomorrow I have much waiting to do at two different doctor's appointments, so I should be able to knit at least one more alien. I absolutely love this scarf, though it rolls more than I'd like. I hope once I'm finished that blocking will take care of much of this.
I'm not usually a big fan of illusion knitting - too much time and too cutesey, or too, well, ugly. But this is perfect.
