Cheap Portable Chroma Key Screen (Bluescreen)

Step 3 Preparing the material

This step is about preparing the material for the sewing-machine. To get a good and strong result you'll have to use a sewing-machine. If you have never done this before, look around if some will help you with this.

Some tips:
- Find someone with some experience to help you.
- Use needles!
- It will help if you stick some parts rough together, remove this after you sticked it again with a sewing machine.

1)
My material was 8 x 1.5 meter. So I had to cut it in pieces to get 2 x 2 meter. Part one has size 2 x 1.5 meter and part two 2 x 0.55 meter (5 centimeter extra for the seam). Use needles to make it one part.

2)
Now we have to create a border at each side to make it strong. Fold 10 cm at each side to a 3~4 centimeter border. Use again needles. At the end the size of the whole screen will be 1.80 x 1.80 meter.

3)
From the rest material you can make strokes. With these strokes you will be able to attach the screen to the frame. I cut it in 64 strokes, each 10 x 25 centimeter. This sounds maybe a lot, but I got on each side 8 attach strokes for optimal span. I fold each stroke to a 3 x 25 centimeter stroke. Don't attach these already to the main materiaal (screen).

The preparing is done!
