I look at it this way...I often buy fabrics because I love them, but I find my tastes change as years go by and a few years down the road I don't love the fabric as much as I did when I bought it and then don't feel like using it. So now I try to use it as soon as I can. If you make it into a quilt you will get to admire it alot more often than you can admire those uncut pieces of fabric in your stash.
That pattern will be perfect for those fabrics. And don't strive for perfection, strive for excellence. Perfection is impossible to achieve. I hope we soon see some pics of your finished quilt!
