(If you want to be a Naruto character in general, use blue fabric.) You can purchase your fabric from your local fabric store. If you don’t have a fabric store near you, you can order it online.  Fabric stores usually have a discount section. If you’re on a budget, check there first. You will need about one yard (36 inches) of fabric so that you have plenty of material to wrap around your head and tie in the back. You can use any type of fabric, such as cotton, linen, or rayon. However, these fabrics will fray on the edges. Other fabrics, such as jersey knit, faux leather, or vinyl will not fray. Of these, knit fabric will likely be the easiest to find in the color you need (and less expensive than the others). Be sure that the strip of fabric you cut is about 3 inches (7.6 cm) wide and however long you need to wrap around your head. Leave enough extra to tie off behind your head.  It would be a good idea to measure around your head first and determine the length you would like your headband to be. Be sure to cut your edges straight. Lay out your fabric on a flat surface and use a measuring stick and chalk to create an outline for your headband. If you have opted for a fabric that frays around the edges after being cut (such as cotton), you can apply an anti-fray aerosol spray to the edges to make your headband last longer and prevent wear and tear.
