Well, yes they genuinely are corduroy... lovely soft, tactile needlecord or pin cord if you prefer and they are part of Amy Butler's new fashion fabrics range.
These are Soul blossom prints;
Trailing Orchid in Blue Velvet... lots of blues, highlighted with a little green.
This is the blue solid which can be used alone or to accent the English Garden or the Trailing orchid fabrics.
They are the same designs as the home decor fabrics of the same names which I'm guessing is where the confusion comes, but these are a narrower fabric as they're 44/45 inches wide (110/112cm) and not 54 inches wide like the home dec fabric. The pattern scale is also smaller.
They can be used to make clothes and bags, pouches of all kinds ....
