I've tried to stay in the same color palette for the entire project so that the finished piece has more unity.
In the bottom right corner is a pressed paper flower from Prima Marketing. These are designed for use in scrapbooking and paper arts but they are very thick and look wonderful on a crazy quilt.
The mauve ribbon is one of my favourites. It's polyester or nylon and I can't remember where I brought it. It is a perfect Victorian mauve and a wonderful drape that makes it perfect for covering seams.
