Read the marketplace minimum in context
Shaoxing Wejoy’s Alibaba.com storefront displays a 1,200-metre minimum on a warp-knit dyed sofa velvet listing. This is a supplier listing, with no confirmed breakdown by colour or backing. Ask for the offered backing, per-colour minimum and whether colour combinations qualify.
Hold the face fabric constant
Request comparable cuttings with the same face shade and construction. Bend both around the same foam edge and note whether one springs back or feels stiffer. Keep backing codes in the sample record.
Match the evidence to the finished construction
Ask whether the existing data cover the exact backing and finish. If the sofa application depends on a particular tear or seam behaviour, agree on how that requirement will be checked before the order.
