boutis

The Provence quilts tend to be made of two large pieces of whole cloth, either cotton or silk, that are sewn together with some kind of filling element, like batting or cording, sandwiched between them.

Today, antique boutis are extremely rare and expensive. Searching the web, I found a great artist, called Pier Laniece, using this technique and creating pieces with her own new designs. Her works can be found here.
