Graffiti quilts

On reading this post on the Subversive Stitchers blog, I remembered my favourite quilt in the 2010 London Quilters exhibition - it's by Veronica Chambers and is kantha stitched -

I also liked this free-motion quilted "graffiti", part of Leah Day's 365-day free motion quilting project -

At the other end of the spectrum there's "Subway Graffiti No.3" by Faith Ringold -
