I went on an all-girl roadtrip in January with 2 girlfriends to another friend's and thought it would be even more fun if we had roadtrippy accessories. I made a cover for my new atlas, a wallet purse with beads on the strap for the cash-pool and receipts and a paper journal for note-taking and mementos.
The little journal came in handy- we made a note of which places had the nicest restrooms (none of them!) and funny things that happened and who got demerits for screwing something up, stuff like that- it became quite hysterical.
The cute road trip fabric is a discontinued print by Alexander Henry, I had a heck of a time getting a yard of it and it probably cost me over $40 for that yard by the time I had it shipped from two places, one in England. I had to have it, though, it was just too cute.
I also made a matching bag for trash that hangs from the passenger seat headrest that was very handy for candy wrappers, water bottles, etc.
Let me just say this- roadtrips with best girlfriends are the BEST fun, ever! We all had a great time and would do it again in a heartbeat!
