Choose your favorite herbs. These could be herbs you grow in your own herb garden at home or bought from the market. Make herb sachets for the herbs you use most or do not want to be in your dish. parsley, bay leaf and thyme are some of the most used herbs around. You can make a blend of the herbs or use each one singly. Both dried and fresh herbs can be used in this way.
You can use both muslin bags or cheesecloth for this purpose. For the cheese cloth, you will have to cut out small pieces. Lay them flat. Deposit some herb (according to your own measurement) in the center. Tie it up tightly using a string. Now leave a tail of the string which you can use to take out of the pot, otherwise you will end up madly looking for the sachet in the dish with a spoon to take it out when used.
As for the muslin bags, such bags are available in departmental stores and mostly used for tea and herbal infusions. They can be bought new, washed and reused. All you have to do is to fill them up. There you have your own sachet collection of herbs which is going to make a lot easier and fun.
