There is some heavy going here, but the important point is “its making requires decisions relating to design, colour, composition and materials, I believe this is art. In addition, if the maker of the work is intending to inspire aesthetic response, to evoke discussion or to communicate an idea beyond the work itself, I believe this is art.”
To me that means that if you are taking part in the artistic conversation by picking threads and/or stitches. Or if you are stitching canvas to inspire thoughts, discussion, or ideas — it’s art.
Don’t let the fact that you needed to use a technical skill in order to create that art change this. After all don’t great sculptors have to learn the technical skills of carving. Do we consider it only a craft because of that?
