I was so happy with the results of the "Little Coffee Bean" cardigan, I couldn't wait to get another one on the needles.  Because the recipient lives in Alabama, I wanted a lighter yarn.  Hobby Lobby's "I Love this Yarn" also has in a cotton blend, making it perfect for this project.  
While the pattern called for Size 7 and Size 8 needles, I felt these sizes made a fabric that was too loose.  I ended up using Size 5 and Size 6 needles.  I do recommend that you use the "super stretchy bind off" for the button bands.  It gives a more even button band, preventing the bottom from riding up.  
Check out Cat Bordhi's video instruction for the Super Stretch Bind Off.  It's super easy to follow and to learn.
