I am going to show you how to make a road trip activity tray for your kids to color and play on.
Step 1: Measure and cut
first measure how tall and how wide you want your trays to be. then take a piece of masenite or 1/4" ply and cut 2 pieces to that size. for my saturn vue I cut 13" by 12".
Step 2: Screw on hinges
next screw on 2 small hinges each about an inch from the sides of the wood. make sure that your screws are not too long and that your wood will close all the way and open to 90 degrees.
Step 3: Drill holes and attach string or cord
drill holes about a half inch from the sides and about half ways down the bottom (tray) part of your wood. then drill two holes on the top piece of wood about 2 inches from the very top. and two holes about 2 inches from the bottom of the top piece of wood. run cord or string through the to bottom holes on the top tray and the in your car see how long it needs to be to tie off to fit around the front see. then run cord through one on the Tray holes and then through the very top 2 holes and then back down through the other tray hole. run the top of the sting under the front head rest and then tie off one of the sides and then put the tray to the desired position and tie off the other end.
now you have a fold up / removable activity tray
