I've finished this sofa last week. It was a hard work, but I love the result. In fact, I need to make two side cabinets for it! :)
This project involved carving, marquetry, embroidery on silk :) 10 different types of veneer for marquetry, mahogany and pearwood for carving and a frame of the sofa. Aaand I had 3 options for upholstery - embroidered cotton fabric, velvet and silk. In the end, I used silk and Chinese silk threads for embroidery.
For cabinets - I'll make "stained glass" imitation and carving too.
