Imagine a three-month knitting party featuring not one, not two, but THREE virtual shows that will have you on the edge of your seat and begging for an encore! At each stop, we sneak backstage with our headlining yarn dyer, exchange tips and tricks, and indulge in a souvenir shopping spree with an outrageous 20% discount.

This is the Ultimate Knitting Showstopper - It's More Than Just Yarn!
But here's the true magic of the tour: It's the incredible people we meet along the way that truly make this tour a one-of-a-kind experience. Our groupies share not only their skills and laughter but also the most generous spirit, forming bonds that rock harder than any band on stage. We've built a community that feels like family, and you're invited to join the fun!
“Love the wonderful things in the surprise boxes! But my favorite has been the zoom meetings – the videos and meeting the designers and getting to meet all the people on the trips.” Ginnie
