Choose a piece of black cloth and cut two layers in the shape of a small person. The shape should look vaguely similar to the person on whom you want to place a hex. Sew the edges together but leave the top of the head unsewn.  Black cloth is best, but if you don't have it on hand, you can use another color. Your poppet should be created from all natural materials. Avoid using polyester fabric or other man-made fabrics; black magic is not as easily conducted through manmade materials. Fill it up with earth, a few powerful crystals, and hair and nail clippings from the person you want to hex. Sew up the head to close the poppet. Draw a circle using chalk or a stick, then draw a pentagram inside it. Alternately, you may draw a sacred circle on a piece of paper large enough to stand on. Light candles around the circle before you step inside. Repeat the words of power three times. Here are a few examples of words you can use to place your hex:  To cast a binding spell and prevent the person from taking actions, repeat "I bind your feet from bringing you to harm me. I bind your hands from reaching out to harm me. I bind your mouth from spreading tales to harm me. I bind your mind from sending energy to harm me." Say this while wrapping the poppet in black ribbon. To cast a love spell over someone you desire, say the words, "Bright the flame. Light the fire. Red is the color of desire." Once they have burned completely, the hex has been cast.

TL;DR in Vietnamese:
Làm hình nhân thế mạng. Lấp đầy hình nhân thế mạng. Chuẩn bị vòng tròn thần thánh. Đứng bên trong vòng tròn và đọc câu thần chú lên hình nhân thế mạng. Để cho nến cháy hết.
