First, you need to be willing to sew a little. Don't worry if you are a novice, this is a great little project to try when you are starting out. I will be using a sewing machine in this instructable but this project can easily be done by hand. So if the task of applying needle and thread to cloth isn't too daunting, gather the following materials -
1 piece of cotton or muslin (loose weave) 4'' x 3'', larger if desired.
12'' of cotton string
2 charms, buttons, or beads (to act as counter weights to the teabag)
2 pieces of 8'' x 6'' loose weave cotton or muslin
And of course needle, thread, and/or sewing machine. Whichever you prefer.
