Beautiful block - the colors you chose go together beautifully and the bison head sets it off nicely. Please post the finished quilt!
For general info: Wyoming Valley refers to the valley region in Pennsylvania around the Wilkes-Barre/Scranton area. A lesser-known Wyoming Valley also exists in western New York in Wyoming County. (I'm an ex-NY State resident who was born in PA!).
The Wyoming Valley block is also on Quilter's Cache, but does not use the loose goose technique (which, BTW, is a really interesting technique and avoids the center seam).
