Minimal latte art technique.

Hey guys, I neither do have a frother, whisk nor any sorta machine like milk steamer or espresso machine or anything. So, using just quick coffee powder and milk give me the detailed process by which I can start practicing latte art. Also, I do not have a pitcher, so I was thinking of a narrow mouthed bottle, open for suggestions. Also it's not that I can't buy any of those, but right now being a student living away from home, I do not have the funds and also those are not too useful as I won't be able to extensively invest my time behind this.

Thank you for reading the full and suggestions and opinions are highly appreciated. ☺️
