You look to be asian? As a result, 1B will be a perfect colour match for you.

When making the template, wet your hair down using water or gel. It makes it easier to put the cling film on your head. Use lots of cellotape to secure the template in position.

Make the template slightly larger that you need it to be. Then over a few days, tweak it, by cutting more...or adding more cellotape.

Don't forget to put

1) The desired direction of the hair (with arrows)

2) Mark the front and back

3) Write the density

4) Write the colour

5) Write your name

Also include a pictures you posted now, so the factory can see what you look like now. And the look you want.

In terms of density, I think you should start with 65%. Then after a few months get one that is 70-75%. Because something would look suspicious if you suddenly had thick hair! what do you guys think?
