I hope I read the TSA rules correctly because my travel knitting includes:

The Garter Stripe Bag that I just finished only in green and charcoal grey.

The Linen Stitch Scarflet: http://www.ravelry.com/patterns/library/linen-stitch-scarflet

And a Cupcake hat from this pattern: http://www.ravelry.com/patterns/library/cupcake-beanie-2

If I can figure out how to post via iPhone, I may check in.  If not, have a great week.
