Arm Knitting an Infinity Scarf

As many of you readers may know...I am really into crocheting different things. I am working on a Rainbow Dash hat for my niece right now. I have seen so many people with these really cool scarves and I have been wanting one for a while but saw the prices of them and **cough, cough** refuse to pay those prices. I instead paid $6 total for the yarn at Walmart and made myself an infinity scarf. I think for my very first one with arm knitting I did a pretty good job. Yes, there are some mistakes but you know what? That is alright with me! What do you think? Would you purchase one if I were to offer them on my etsy store?
