Half square triangle quilt

My friend and I collaborated on my friends customer HST quilt. The customer had pieced the HST blocks, then life got in the way of completing the quilt. She sent the blocks to my friend. We came up with the layout and my friend pieced the top. The customer wanted a queen size quilt, so we added borders. The customer wanted all white added as a very large border, but I thought of the blue border with HST in the corners. The customer loved the border and wanted white added as the rest of the border. The colorful part of the quilt is on the top of her bed and the white drapes on the sides of the bed. 90" x 100"
