I tried hard to find a relevant stackexchange site for this question and this seemed closest.
I have a wool winter jacket that has been stored over summer and on pulling it out of the closet I discovered what looks like, I am guessing, moth damage. See below:
There are no holes but it seems the “fluff” from the yarn on the herringbone has been removed.
Is there any way to revive the wool and return the texture to the yarn?
