Carbon+Water+Net

Carbon - a fantastic Water Filter, removes heavy metals, chemicals etc. the stuff I have got here is made for cleaning fish tanks. It is incredibly beautifully black 

It sits nicely in this Camira | Camira Fabrics recycled polyester 

And gives that old net curtain some structure if I sew it in 

My intention is to sew it into fabric to act as shelter, filter and structure at the same time. 

I would like to try it in some other fabric - perhaps the nettle and wool mix - also from Camira
