Takes some time. Feed her energy, I assume you're familiar with the basics of energy work? If not, I'd learn that first.

The guy asked how to create a tulpa, not whether making a tulpa is a good idea or a bad one.

Be careful what you wish for.

However, most tulpae do not tend to attempt takeovers from my experience. The meme post from /fringe/ was also likely a LARP.

what if it wasn't a larp?
would you bet your life or even soul on it?

If it was reality, then it is an example of what inexperience combined with dangerous levels of fetishism can do.

In the end, that person wanted and created the tulpa for that purpose, through feeding it his desires.
