I have a brown paisley bandana, but when I went to knot it at my nape, it was a real tight tie. It measures 21 by 21, after machine washing & drying.

Are there bigger ones on the market, & where?

Are there on-line or store-bought instructions for how to use bandanas other than (1) folded up & placed along the forehead, put under the hair & knotted at the nape & (2) folded in half into a triangle, put under the hair & knotted at the nape?
