okay have you done any purling yet? couldn't tell for sure from your post.
you might want to go to www.knittingpatterncentral.com
and check out the patterns there. maybe a more complicated scarf? i am always an advocate of hats (i have only ever knit hats in the round and it reeeeeeally is very very easy!) dishclothes are always good too.
dive in...you will find lots of help here! don't worry about the pattern...if you are brave you will get all the help you need here. if you are a little more timid don't do anything TOOO scary cuz you don't want to get frustrated and quit! we will help you all we can....i promise!
