I tried recycling some duvets for padding my wig head and for using the shell for drafting.
They are supposed to be 100% wool filled. They were not. I now have splinters from whatever filler was added and not listed. So now I get to struggle to get the high powered vacuum cleaner to my workroom and I’ll probably have to wear a dust mask while doing so.
And this is why labeling fibres is so important. I hate that there is about 5% that can be unaccounted for. That could be glass fibres you know.
