At home I have a designated dye area away from other people and animals. I use professional acid dyes and I use citric acid to set the dyes.
I kettle-dye, dip-dye and handpaint the yarns in small batches, and most of our colourways are repeatable. Sometimes I love to try out new techniques or colour combinations. Then you will find ooak (one of a kind) colourways in the shop which are not repeatable.
While I live in a cat-friendly home, I take special care to ensure that no felines are present during the dyeing or drying process. Despite all of my precautions, I cannot guarantee that my yarns are 100% dander-free.
