There's been two popular news stories this week which have brought all this into focus for me. Both make interesting reading for us fibre users and have made me think a bit harder about my yarn choices.
I'd be very interested to hear your thoughts on the subject.
The first article is about the presence of plastic microfibres in our drinking water - the source of the fibres and their effect on us (if any) are not yet clear. Synthetic materials used in clothing and home furnishings are suggested as a likely source.
The other is a piece from Prince Charles (patron of the Campaign for Wool) extolling the virtues of wool in many applications.
