A Kiddie Car Meal Tray
Kids tend to be messy eaters at the best of times, so in a car there really is no telling where sauce will end up or if you will find a chewed up carrot stick on the floor mat, and if you are thinking about going through a drive-thru you should be prepared for the upcoming mess. But kids gotta eat, especially on long drives, so save yourself the mess (or at least a large part of it) and get a couple of cheap organization buckets, and you have yourselves a kiddie car meal tray.
DIY Dog Seat Cover
If you travel a lot with your dog in your car, then you know what it is like when they traipse their muddy paws onto the back seat, leaving dirt and dog hairs everywhere, making it pretty unpleasant for the next passengers and making you work every time you take your pooch on a little road trip. Save yourself the hassle and just stretch out a twin-sized bed sheet over the back seat and tuck it in well on all sides.
