Knitting is very soothing. It is something between meditation and fiddling with your hands. I was stuck in the Dulles airport for a day and a half, and having knitting with me kept me sane, kept me watching the riot forming at the ticket counter with quiet amusement. These mittens are for my 2 year old. I did them on two needles, because I have a hard time with double-pointed needles. I also journaled about my trip, drew pictures of costumes I wanted to make and strategized how I could get my entire family including my parents to come to this same science fiction convention next year. I had it so worked out that I was surprised when my Mother didn’t seem as enthusiastic as I had imagined.
You can be creative anywhere. All you need is time and thought. Yarn helps too.
