Linen for shield fronts?

[hoplite14gr]

A plausible scenario: wickerwork covered with linen layers the external layer could be treated with pine raisin for waterproofing.
You didn´t also nee to kill an animal to get hide.
Could have happened since basket makeing could be awider ranging skill than carpentry and metal working.
Interesting option for a psilos who could have looted the lined if he could not afford it.
Kind regards
