At the last meeting of a local group of contemporary quilters we made bowls using a sort of iron on vilene type stuff called, I think, fast and fuse. (Does that sound right?) It involves cutting squares of fabric and f&f, ironing the fabric on, cutting slits, like darts, and stitching the edges together. The corners of the square can then be trimmed to a more interesting shape as desired. Have seen these 'vessels' on another blog recently but cannot remember whose! I'm very sorry. There are books about them. How vague can one get? Let's move on quickly to another post.
