Willi, permit me to suggest a sacriligious solution., Go to Walmart,
and buy some "Needloft Plastic Canvas Yarn." White or cream or yellow,
or any other color you like.

This could also be done with the poly yarn sold in fly shops. For a much
higher price of course.

I like the Needloft yarn because it is stiffer. Ideal for wings and
posts.
