I take some kind of needle work on the planes to pass the time too. I have a baby blanket that got too big to take (crochet) and I am bringing some yarn to knit a scarf for ME. Maybe I will finish it before we land and I can wear it in Italy.
I will probably pack a Sudoku book too. Those puzzles are very addicting. I used to do those word search puzzles on planes. This might be more challenging. I've been afraid to start the daily ones in the newspapers because between reading LCT in the morning and the LA Times, I might never get to the office at a reasonable hour.
MarnaLou, If you haven't learned by MUSH (I think you are going?), I can teach you.
