Perhaps 2-4 years ago there was a post wherein teabags were used for the wings of dry flies. The poster made the point of stating that he was using UK tea bags, which are made from a material different from that used in American teabags. I went found some British teabags in the international aisle at a local store and bought a box. They are a good bit more expensive than what I am used to, but the tea is MUCH better and the teabags seem to be made from a different material.

I had to post an entire paragraph to set up my question. What, if anything, is done to treat the now-empty tea bags before cutting them and tying them in as mayfly wings? Thanks in advance. (Yes, the tea has been removed.)
