Fabric is the only part of a wardrobe that is certain to be changed within its life. Timber lasts decades, carving lasts longer, a good finish can be revived - but a fabric panel will eventually be tired, or simply wrong for a room that has been redecorated around it. So the question for the maker is not how to fix the fabric down. It is how to make it removable.
The wrong answer, and the common one, is to stretch the fabric across the back of the door frame and fix it there. It looks identical on day one. It also means that changing the fabric requires taking the door off, stripping the fixings out of the rebate and re-fixing into timber that has already been perforated once - and after two or three changes that rebate no longer holds.
So our master Indian artisans build each fabric panel on its own separate sub-frame, stretch the fabric over that, and then fit the completed panel into the door with a removable bead moulding. To change the fabric you lift out the bead, take out the panel, and re-cover it on a bench - the door itself is never touched and never weakened.
It is a small decision made at the beginning that decides whether the wardrobe is still yours in fifteen years.
