Order confirmation email advanced template

Hello there!

I’m trying to extend the order confirmation email to the following in the DESCRIPTION column (for each of the line items in the order):

DESCRIPTION

Product Name
Manufactured by: XYZ
Property 1: VALUE1
Property 2: VALUE2
Property 3: VALUE3

Where I can find reference to code this template? or is there any built template that can help me?

Thanks

Forget it. I used variants.
