Are you on Ravelry? I love their pattern search function there, and found this easy-looking no-sew short-sleeved shrug:
This one has 3/4 sleeves: http://www.lionbrand.com/patterns/glamknits.html
Here's a long-sleeved one: http://www.canadianliving.com/crafts...bbed_shrug.php
Ravelry lets you choose difficulty level, and the type of yarn you have, so it's pretty easy to find something you like. They also flag the patterns that are available for free.
