Preparation tools: worn-out clothes, (broken pants are shown here) rags, needle and thread, scissors.
1. Put the prepared broken trousers on your body, then put the rag at the position of the break, and cut a piece of rag with scissors, preferably in a round shape.
2. Fold the cut circular rags in half, and then cut out the shape of a heart.
3. Put the shape of the cut peach heart in the break to try whether it is appropriate or not. If it is not appropriate, modify it.
4. Take off the broken trousers, and then sew the heart shape of the cut rag on the broken part with a needle and thread. You're done.
