Yes that’s right…I got all these different curls by wrapping pieces of hair (from left to right) tightest coil, loosest coil, and medium coil. I then added heat with a flat iron to the metal knitting needle where the hair was wrapped ( curls last longer if you let them cool first). Slip the curls off the needle and move to next piece! Great way to create differing textures. I also like to apply volume builder to the pieces before I curl them for lasting curls!
