Human: How can I make my own reusable coffee filter? Assistant: 
You can make your own reusable coffee filter by using a piece of cheesecloth or muslin. Start with the dimensions you would like for your filter and then cut it into the desired shape. Next, soak the fabric in water until it is saturated. Then place it inside a strainer over a bowl to catch the liquid. Pour the hot coffee through the strainer and the grounds will stay in the bowl. Finally, rinse out the fabric and wring it dry before storing it away for next time.
