Knitty.com has a wide variety of patterns that I have found engaging to work with. I recently knit a pair of cargo pants for a baby boy from a pattern found on knitting, and am now working on a little orange and blue fair-isle pattern dress for a baby girl. The site has tons of different patterns and articles for knitters to make items such as simple to intricate scarves, to stuffed animals, to knit clothing. Each pattern is rated on difficulty level in terms of spiciness - very cute! I also like that in each pattern there are links to knitting vocabulary/abbreviation pages, articles with more information on specific techniques, and helpful tips - way to make use of cross-linking on the site.
