I think this is what you want.
step1-Decide where you would like to install your feather extension, then peel back a layer of hair to expose the roots. Gather a small strand of hair in your fingers, and make sure the roots are close together. step2-Wrap the wire tool around the strand of hair. Take the two ends of the wire and thread them through the crimp bead. Pull the hair through the bead with the wire ends. step3-Slide the crimp bead to the hair roots and carefully thread your feather bundle through the bead. Make sure the feathers stick all the way through. step4-Use the pliers to firmly crimp the bead. To ensure comfort, crimp it in a way so it will lie flat against the head. If necessary, trim extra feathers sticking through the bead with scissors. step5-Your feather extensions should stay in for 2-4 months. To remove them earlier, take pliers and gently squeeze the crimp bead in the opposite direction until it is approximately O-shaped. Then, remove the feathers and slide the crimp bead out.
