Wow, I purchased a size 4 & 5 Yarn & Colors hooks. I was pretty thrilled that Stasia decided to stock these as I was looking at them on the Yarn & Colors website. I thought it too much hassle to purchase from overseas given there a massive delays with overseas post. I tried theses hooks on the Yarn & Colors cotton that Stasia stocks and oh boy it was so good. Firstly the cotton yarn just glided fluidly over the shaft part of the hook and secondly it’s a seriously very ergonomic hook. I was using an other brand name hook for my cotton stash and it felt like it was sticking and causing me to use my fingers and hand harder. I have Arthritis in my hands so this a welcome relief.
