The Sorcery Shop is back at it again with a fresh Thread Boss Refill, now featuring a brand new centre core and snazzy new bands. You’re looking at over thirty feet of their spectacular Ultra Fine Wooly Nylon thread (seriously, it’s like thread from another realm).
And don’t worry, they’ve thrown in some handy tools and instructions to help you patch up your thread boss and swap out that centre core like a pro!
