Last weekend I went to a fibre fair in a rural town. Although i love dyeing my own yarns, especially with plants, I couldn’t resist buying some skeins of 70:30 merino:silk yarn dyed by hand by the seller with what was described as “an eco-friendly acid dye”. [I have not researched this since the dyer could not recall the name of the product (!) and I’m guessing I might be disappointed at what I found – but then, I’m cynical]
On this occasion I am not worried because I work small and quite like variations in any case. However, it would annoy me if I had bought the yarn for a garment!
The lesson here is to look closely at the skeins before buying them unless you know the product and can be sure that it’s been dyed correctly.
