Under normal circumstances, I am so busy my husband calls me a hummingbird. In a car, I become a caged tiger.. a case of restless leg syndrome takes over my entire body. So I have learned to prepare a project to complete in the car to keep myself occupied instead of insane. I have worked on quilts, tied labels for my Anthropologie order, made cards, and this latest trip to Portland... decorated postcards.
To prepare, I cut some discarded album covers into postcard dimensions ( First-Class Mail postcard: At least 3.5 x 5", no more than 4.25 x 6" x 0.016" thick). Cereal boxes also work. I put these in a zip-lock bag with glue sticks and scissors. I also bring any books that would be better as images. Children's encyclopedias or science books are awesome as the illustrations are precise but outdated to assuage the book-destroying guilt. Many children's books have brilliant graphics and insipid text... And you can make gift cards from the pages too. Avoid reading, naturally, to deter car sickness.
Leg-stretching stops can occur at thrift stores to find more image resources.
And thus I am amused for hours with hilarious juxtapositions: angler fish with the Andrew Sisters, John Travolta with a shark dance partner, Puffins in space....
....Happy travels this holiday season!
