The links below will take you to a fabric manufacturer's website where their free patterns are listed. They have some great patterns, for all skill levels. The link will open in a new window.
Check the sites regularly as they constantly add patterns as new ranges are released. Of course, you don't have to use exactly what they say - you may have the perfect fabric already in your stash!
