Wow... I love it too! The pinks and blues and purples are a great combination. I did a king size batik in pinks and dusty blues ("Not Your Grandmother's Log Cabin" design) for a 90 year old aunt and trying to finish it off was a real hassle and I was not fond of the quilt until it was totally finished and quilted... now I am very happy that my friend and I chose the colors we did and put it together for my aunt who absolutely loves it! Wish I'd used more of the deep purple because I LOVE the contrast but my aunt was more into country blue and pink/mauve colors so it came out very well.
Good luck and keep telling yourself, "one more block for my sister"... you'll be done before you know it and she will be very happy you "stuck it out for her"...
