Last year I grew Coreopsis flowers, organically, in my garden, and you can see them flowering in my video in the 'about' section of this Etsy shop. I also have a blog entry about Coreopsis. Coreopsis pack a punch in the dye bath, as this wool gives example of! It's golden, with orange undertones, a really gorgeous colour. The great thing about natural dyes is that they all go together, whatever colour they are. Nothing jars as it's all natural. This is the same base yarn that I use in all my 4ply natural dye collection. It's super wash which means you are supposed to be able to wash it in the machine. But I never do.
