This is Water's Edge, designed by Marion Patterson in the quilting book, Simple Stitches Quilting. I did add the borders around it though. This quilt is black, white, grey, and purple. I totally changed the color scheme so that would be why this quilt doesn't really look like the "Water's Edge"!
I only have one complaint for this pattern: if you don't use a layer cake (40 10" squares of fabric pre-cut) it is best to lay out the pattern as you cut your fabric and the pieces that lay horizontally you'll want to cut a 1/4" shorter.
You can purchase this quilting book which has "18 projects for the new quilter"! I just received it as a gift and have found many patterns I am anxious to make.
