I love Bonnie Hunter's website, as mentioned above. Every time I go there I want to make a differnt quilt.. I love scrappy quilts, they are my favorite.
I think the thing that makes scrap quilts too chaotic sometimes is if there isn't a light background, or at least a solid color for your eye to rest on.. if it's all just a jumble of color I find them less pleasing than if there is sashing or a background to give it some peacefulness in the midst of the scramble.
