Truckers are among the increasing number of men who have taken up the manly art of knitting. Knitting helps to fill in trucking down time and has gained a lot of popularity with long haul drivers. One fellow, Tom, sells his knit socks through his wife's Etsy shop. Another fellow, "The Knitting Guy" was keeping quite a nice blog until his mother died, but the old posts are interesting.
Knitting isn't the only needlework occupying truckers' minds--several have taken up sewing as well.
