The challenge of doing a shattuck-tripoli duotangle was fascinating for me because shattuck is one of my go-to tangles and tripoli is one I've always struggled with. Fortunately both tangles wanted to tango on my tile and always knew exactly where each wanted to me. The challenge for me was how to bring some definition to all those hundreds (thousands?) of tiny lines. I think this works. I love how doing these weekly diva challenges brings out different sides to my creativity!
