Handmade using fine linen thread or wool yarn (wool comes in a little cheaper as the yarn is heavier so works up a bit faster. Your choice of dyed or undyed wool), our sprang hairnet is a good consideration for very late Neolithic through Bronze Age styles, though the technique does survive into the medieval period and beyond in some areas. Our nets are largely modelled on Bronze Age finds. 
 
Quite a variety of stylings possible with these, and each will be unique, but a few recent ones shown in the picture. If you'd like me to work from a specific example let me know. 
 
As with all my made to order hats, please allow up to three months for me to make this for you though I am often much faster.
