Step in, relax, have a glass of wine.
Over the holidays I knit two wine bottle sleeves and sixteen coasters. They were great travel knitting because both bottle sleeves and coasters are relatively mindless knitting. I used circular needles for everything so I wouldn't have to worry about dropping a needle on the airplanes. I did need to get home to felt them, which was fine as I've been in and out (and in and out) of town for the past month.
I knit one bottle sleeve larger and gave that one away before I could take a picture. Below are some in progress photos.
And here is a link for a free pdf of the patterns.
