I also love watching this show. It is amazing to watch some of the designers who use couture talents to make thier garments. The others use what is called, fabric draping on the dress forms, a few basic templets and tools.
It is amazing what you can make when you have a dress form. It is world's apart from making something from a comercially made pattern and not knowing if it will fit in the right areas. (If you know what I mean, LOL!) I would like to go and shop at some of the places they get to shop at for fabrics.
