It's Sew Emma의 십자수 키

I've been using this cross stitch key for a few weeks now, and the floss count reference guide is incredibly handy—no more digging through drawers for a chart. The compact size fits perfectly in my project bag, and the needle size info saves me time when starting a new pattern.

Finally, a reference card that actually makes sense to keep with my stitching supplies. The needle size guide alone saves me from digging through separate charts every time I start a new pattern.

Took it to my stitching group and everyone wanted to borrow it — the needle size guide alone saved me from guessing on a new project.
