this is a quilt I'm now hand quilting that is based on a pic of Victor Vasarely op art the Harliquin , I see that Anna Faustino has a book on a high tech way of doing this background but mine is low tech , one piece at a time,I look forward to seeing how she does it all , I finally took pics at every step and am going to make a slide show of the making of it , it should be finished in about a month, I am quilting it with the 4 of the world's hardest mazes on the back , I looked at the pic for 15 yrs before figureing out how to make it ,
