How can I make my own reusable coffee filter?
assistant
To make your own reusable coffee filter, you will need a few supplies. You'll need a clean cotton t-shirt, scissors, and an iron. Begin by cutting the shirt into strips about 2 inches wide. Next, fold each strip in half lengthwise, then fold it in half again. Finally, iron the folded strip to flatten it out. Once you have completed this step, your reusable coffee filter is ready to use!
