Introducing the Mystery Thread Box!


Building on the success of the Studio 7t7 thread, many customers have asked for more options. A 7t7 club member requested a mystery thread box and so the Mystery Thread Box was born!


This is the pre-order of the thread box with shipping estimated at the end of August 2025.

Why pre-order? Previously one off boxes have sold out. By offering a preorder we can gauge interest and be sure to account for all who would like a box by letting you secure your box before we order the threads. There may be additional boxes available after the pre-order cut off but this can not be guaranteed.

To avoid disappointment please pre-order.


Note: This is a one off box of thread, not a subscription.
