Your quilt is very nice! I did some searching on the web and discovered that Kathy Brown designed this beauty for the August/ September 2012 issue of McCall's Quick Quilts. I like her designs. :-) Otherwise, I have no connection to the designer.
Someone on ebay is selling the pages only for that pattern..... FYI Kathy's website does not list this pattern.
