Threads

Stitchkin identifies threads by the numbers and names of the DMC palette, so that a chart written in those numbers can be read. DMC is a trademark of its owner. We are not affiliated with, sponsored by or endorsed by DMC, we sell no thread, and the numbers appear here for identification only.

Chart file formats

The app opens files produced by other programs so that charts you already own can be used on your iPhone:

Those companies are not affiliated with Stitchkin and do not endorse it. Reading a file format is interoperability, not a partnership: no code of theirs is used, and the app cannot write their formats or copy charts out of them.
