They are here! The KNITS size markers.
You know the feeling when you've needed the needles from a UFO* and borrow them, to return to the project later on and realize you have no idea what size needles was used?
Attach this marker to your project and the problem is solved!
The decoration is two sided - size on front side and on the back side texts: "one more row" and "KNITS.fi".
*UFO = unfinished object
