Here's my completed Vikings Modern Improv Pieced Quilt top. It is based on Score #10 in Sherri Lynn Wood's book, The Handbook for Modern Improv Quilters.
I decided to trim it down to get it a bit more symmetrical since it was obviously wider at the top than the bottom-- a 1.5 inch difference. It's still not exactly true, but at least no longer obviously asymmetric!
