I remembered you stated on one of your blogs on how difficult it is to find good gradient yarn. I remembered you liked Wendy’s Wonders. I use gradient yarn in my colorwork knitting also rather than using individual skeins for fades (hate weaving in ends).
Have you ever used Wollelfe merino/silk yarn (https://wollelfe.at/en/merino-yarn/merino-silk-gradient-fingering/) or Freia Fibers (https://freiafibers.com/product-category/yarns-by-color/ombre/)?? They are gorgeous yarn bases with amazing colorways and soft transitions. I thought of you when I was buying my recent splurge!! 🙂
