I frequent the web site of material obsession and I saw a quilt on there made by a wedge ruler designed by Marilyn Doheny. It is such a cool concept. I do not know if I am going to make a quilt with these rulers but I did start making a block. It is not completed but it is a good way to use your scraps. This circle is being made from the 9inch wedge ruler. I may just make a mini quilt of it right now. It is an interesting concept and the rulers come with many quilt pattern ideas.
