Every button on this diwan is made in our workshop, after the covering is already on the piece, and both of those facts matter.
A covered button is a small thing that goes badly wrong easily. Cut the cloth for it square to the weave and, on a patterned fabric, each button ends up showing a random fragment of the design - a piece of leaf here, a corner of a flower there - so a field of forty buttons looks speckled and busy. Cut on the bias instead and the weave reads as texture rather than as chopped pattern, and the buttons recede into the surface where they belong.
The timing matters just as much. Fabric varies between rolls, and even between the beginning and the end of the same roll. A button made from a different piece of cloth than the covering will sit slightly off in tone - not enough to name, enough to notice.
So the buttons are cut last, from the offcuts of the very covering that has just gone onto the piece, and made up while that work is still on the bench.
Forty small decisions that nobody is meant to see individually - only the calm surface they add up to.
