It is called "Sunset" by Julie Popa. The pattern is pretty easy as there aren't many seams to match. I took this as a class and was suppose to choose totally random color stripes . . . but just could not bring myself to do that. Now I've recently discovered this pattern on Quilters Cache (Irish Plaid) but with a much more desireable border. Of course the Irish Plaid uses 3 stripes and the Sunset just uses 2 stripes. This was my 6th quilt and all the ones before were baby quilts. It's the only one I've kept so far and love it so much, I made a jacket with the scraps.
