When my dad died my brothers and I went through his fly tying stuff. 4 large chests plus a tying bench with shelves full of materials. You couldn’t tie a woolly bugger or crackle back out of it. My brother asked if he could have it and I said “yes, thanks”. 😂
I was talking to him a year later and he said he ended up dumping it all. Couldn’t even give it away.
