Yes, that's right - one of the benefits of being known as an artist is that you can call things anything you like! Lucky accident, it turned out okay - it's a cardigan. Have no idea what you're doing only one sleeve and no neck opening - freeform art symbolising the death of chivalry 😊.
Perhaps an idea is to create a decal or centrepiece for the back (possibly a more simple pattern for the fronts and sleeves, picking up motifs) and then knit or crochet it into a garment. Alternatively, create a garment using intarsia knitting technique - this is what I was originally thinking with the ideas from the Revolutionary Art post.
But I am also taken with your mixed media ideas - perhaps some is knitted/crocheted and perhaps some is coloured with dyes or bleached.
