To make tea bags: With sharp scissors, cut fabric into a square about 6 x 6 inches. Cut a piece of thread/twine about 17 inches long.
Place 1 teaspoon of loose tea in the center of each piece of fabric. Gather up fabric around tea and twist. Tie with kitchen twine, securing with 1-2 knots. Cut off the excess top fabric. Repeat as needed.
To make personalized tags: Have assembled tea bags nearby. If threads are very long, trim slightly.
Fold various colors of cardstock in half. With the cardstock still folded in half, cut out two identical shapes with scissors or a medium- to large-sized decorative hole punch.
Rub glue stick on one of the two identical shapes. Place one end of the kitchen twine (attached to the tea bag) on the glued shape. Place the other shape on top. Sandwich together and press for a few seconds. Cut string of other end of twine, not attached to tag. Set aside and repeat.
With a fine-point Sharpie or pen, write the title of each tea on the tag.
Twist the twine around the top of each tea bag (where you knotted it) to keep from tangling.
