I love Shibui- very easy to work with and pretty colors. I like the Staccato a bit better because the silk adds a bit more softness than just the sock. I needed the Jackie color though to finish a project, so had to go with just the wool and no silk.
I am slowly building my interchangeable set and Addi makes it easy by being able to purchase just what is needed. The Addi's are smooth. Sometimes the part where the two pieces connect get stuck on the yarn but just push the yarn and it's fine.
