Skirted upholstery went out of fashion for a generation and is quietly coming back, and the reason it went away is worth knowing. Mid-century furniture wanted to show its legs - the whole aesthetic was about lifting things off the floor and letting light under them - so skirts were cut off and aprons exposed. Everything before that had been skirted, because upholstery to the floor was warmer, hid the frame, and looked more substantial.
Neither is right. They do different things, and the choice should follow the room. A skirt in a large formal room settles a sofa and stops it looking marooned; exposed legs in a small room let the floor run underneath and make the space read as larger.
The craft point is that a skirt has to be pleated to the shape of the frame, not simply hung around it. Our master Indian artisans set the pleats out so a full box pleat falls at every corner and at the centre of each run - which is what stops a skirt looking like a loose cover rather than part of the sofa.
