I just finished the top for a batik kaleidoscope quilt (by the way, the Marti Michell ruler is fabulous!). Here is the sample from "American Patchwork and Quilting":

The question is: is it a complete failure? Is the contrast so low the pattern doesn't show up at all? I'm rather disappointed, and once I had made a few blocks I realized the fabric selections were not optimal. But, I had cut out all that batik and it went together in five or six hours so I completed the top to get some kaleidoscope practice.
I suppose I can use it for quilting practice. But that raises another question: what color thread?
