What is your favorite type of project to take along on holiday/vacation?
I don't have a favorite... I just take whatever I'm working on at the time. I don't have a set rule for what makes travel knitting... I've taken big blankets to knit on in the car!
Though, I guess I do like socks, scarves, and smallish stuff like fingerless mitts just because they are convenient in the car. I tend to overpack when it comes to yarn and such and will take enough goods for 5-6 projects on a weekend trip!
