Cold Brew Coffee at home? How to create a cold brew coffee filter at home, I've seen so many "brewers" but all were not affordable by me nor deliverable in my location please help me?

This question is not a duplicate of Choosing filter for making cold brew am asking on how to build a cold brew itself?
One method is to use submerge your grounded beans in water for 24 hours and use a traditional cone filter.  Place the filter in a pour over cylinder if you have one and that will remove the grounds while leaving you the sweet, sweet cold brew nectar.  If you don't have  cylinder, you can definitely use a filter in your desired cup, just be careful with how you place it.
