Find your perfect project

We believe that there is a perfect project for every moment in your life. Meditative projects are perfect for morning ritual or an evening in front of the tv. However, sometimes you need a challenge to motivate you or practice your concentration. Big afghans can keep you cozy while knitting in the winter. Smaller projects are perfect for traveling and waiting for kids. Take a look and see what calls your name. Let us know if you have any questions.

I just finished a fingerless mitten class and it was phenomenal! Liz was patient and funny and full of helpful hints. I normally cast on by " knitting" on.. she showed me how to cast on by thumb and today I did it on my own for the first time!!!

Super cute yarn shop! Nice selection of yarn, lots of visible samples, and helpful staff! You can find neat crafted accessories from cool vendors, like project bags and various supplies, too. Great shop!
