I really love this pattern! You can have so much fun with colors, patterns, and fabrics. I used EIGHT different fabrics in mine. And yes, I used BROWN! Brown can play really well with lots of colors, so give it a shot sometime.
AND, did you notice? Today I've released the March/April 2015 issue of Hexie Love - see the link above! I hope you enjoy and have a happy hexie day!
