I'd take a look at the free online pattern Wild Orchids by Northcott, (www.northcott.com). The pattern is in the archived section under the pattern button and is by Jean Ann Wright. It's an easy but very striking design and I have just finished two of these quilts just using purples of every shade and hue. The original pattern is smaller but I just made more block units, each block unit being 18 1/2". The queen sized one I made I used 4X5 blocks before borders and the king sized 5X5 which was 90X90 before borders. This quilt would be just as great using all of your fabrics and is very easy to stitch and quick to cut if you lay the cut strips and rectangles in piles as you go. Happy stitching!
