Car Back Seat Organizer Made from an Old Jacket

Supplies:
A Jacket (the fabric should be thick, you can also use any upholstery fabric instead)
Bias tapes, or regular tapes (for finishing off the raw edges)
Sewing supplies

Tutorial:
Take the measurement of the back side of the front car seat. (Height 24" and width 17")  Place the jacket on a flat surface and cut one piece that equals to the measurement of the back side of the seat. This is going to be the main panel of the organizer and you also need several medium and small pieces for making pockets. I used the backside of the jacket as the main panel. Three medium size rectangle pieces (referred to as pocket #1) and several other small size rectangle pieces (referred to as pocket #2) are cut from the same jacket fabric.

You also need regular or bias tapes to finish off the sides. See my previous tutorial if you want to make your own bias tapes.

How to make regular tapes and how to attach them?

Cut a rectangle strip anywhere from the fabric (a contrasting color printed fabric is used in the project)

I used 0.5 " wide strip for finishing off the edges. If you want to make a tape of 0.5" wide, you should start from a 2" wide strip. Decide the length of the strip depending on the requirement.

Place one 2" wide strip, with the wrong side facing up. Bring the two long raw edges of the strip to the center to make two folds and nicely iron.  Then make one more fold, length wise, along the center and iron. At this stage you can call it as a regular tape.

Attaching regular tapes: Place your fabric with right side facing up. Bring in the regular tape and sandwich the raw edge of the fabric in between the folds of the bias tape. Pin in place (you may also flip the fabric and make sure the pin has secured the back side of the bias tape). Sew along the folded edge of the tape to finish off the raw edge.

Attaching pocket #2 to pocket #1 
Get the small rectangles pieces cut for pocket #2 and and finish off their top raw edge with a regular or a bias tape. Then, place and pin pocket #2 onto pocket #1.

Sew along the remaining three edges of pocket #2. I used a straight stitch followed by zig-zag stitch to secure pocket #2 onto pocket #1.

Similarly, prepare the rest of the pocket #1.

Attaching pocket #1 to main panel
Finish off the top raw edge of all pocket #1 with regular tapes. Arrange all three pocket #1 prepared on the main panel.

Then, pin them in place.

Sew along the remaining three edges of pocket #1. I used a straight stitch followed by zig-zag stitch. You can also compartmentalize the pocket #1 to smaller pockets by making a straight stitch on the top of pocket #1. Finish off all the four edges of the main panel with regular tape or bias tape.

Attaching handle and fasteners
I am going to hang the organizer to the two rods that is in between the head rest and the car seat. Also, need two fasteners to secure the lower side of the organizer to the seat.

Decide length of the handle required and cut two strips of 1" wide from the same fabric. Attach them together by straight stitches along all four raw edges. Finish off the raw edge by regular or bias tapes. Attach the ends of the handle to the back side of the main panel.

To make the fasteners, a regular tape of 0.5" wide, is used. Sew along the folded edge to make fasteners.  Attach the fasteners to the lower backside of the main panel. 
To hang the organizer, slide out  the the head rest from the car seat and place the handle. Then, slide in and snap the the head rest. Tie the ends of the two fasteners on the lower back side of the car seat.

Organize cell phone, tablet, sticky notes, travel games, head phones, pen/pencil etc. in different pockets of the organizer.
