After much debate and going through my queues and pattern library, I finally decided to make the Garter Stripes Bag. But, as I cannot bring a pair of scissors on the flight, I plan to knit this in one piece (well, as much as I can) by picking up stitches along the sides.
I'm on the third square here and I've been successful so far, although after picking up the stitches for the second square I realised that I was facing the wrong side. So instead of knit every row I purled every row, and it worked!
This is the back of the piece, the edging is quite neat, and no sewing up so far :)
Oh, I'm using bamboo needles, so fingers crossed that the airport security won't confiscate them!
