making my first template and I have a few questions.

1. How closely does the template have to mirror my scalp? (I have long but thin hair on my head, so I couldn't get a template that exactly replicates my actual scalp)

2. After I finished taping up the template, it started getting a few crumples and creases. Will that affect how the factory makes the hair piece?

3. Does the factory follow the line I traced on the template or do they follow how I cut it?

4. Do I need to write down the measurements of my scalp?

Thanks
