I have spent the last couple of days doing a class with Cathy Doughty of Material Obsession what a fun few days I've had. The first 2 days were the quilt Soul searching which is a real exercise in colour. The yesterday I did just one block of using templates a very accurate way of cutting blocks. Also have a look at Cathy's blog materialobsession.typepad.com
