I'm working on a child's scarf (to match a hat already finished). I keep it down in the laundry room and polish off a row or two as I wait for that last five minutes or so the machine needs to finish.
I've got a new pair of socks in the works. I keep it in a baggie, next to my bed. I do most of my reading in the morning, and most of that from my NOOK. I work on the socks a little bit at a time, between pages or when something is downloading. I have finished the ridged tops and am now at the round and round part. I try to finish at least one round on each sock each day.
When I go to my sil's house, I bring smaller projects with me--or parts of bigger ones. Like the snowflake quilt I'm making for my daughter. One motif at a time and eventually I will get the whole thing done.
If I want something that is 'mindless' and doesn't require looking at the directions, I just bring my needle/scissors 'chatelaine' (See link below) and a few projects and weave in some ends!

There may not be time to do it all, but there's often time to do a little!
