Give the Gift of Hope

Hello, Hope 2024

Imagine that you were able to travel across the world to Rwanda to meet the incredible women who work at Handspun Hope, making gorgeous yarns in a beautiful, earth-friendly way.  

You would have bought these souvenirs to support their efforts and to remind yourself of the good happening in the world.

And while you might not make it to Rwanda, you can still be a part of their story of resilience and creativity with your purchase.

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!!!

Andrea D.

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!
