the only problem i had with microspun was that it split easily. but it's really soft, inexpensive, and has nice colors so i lived with it. i'm probably going to use it again but in a different color so i can make a branching out scarf for a friend.
i used size 7 needles. it came out a bit shorter than i expected.
here's the only picture i have of my finished scarf right now. i used "mocha", the color is actually lighter in real life. it looks a bit wavy in the middle but it's not, i was just too lazy to straighten it:
