Oh boy do I know how you feel Sletinski!? The same thing happened to me. I made a polka dot basket quilt with a white on white polka dot background. Just as I was starting this project all the fabric manufacturers of the world decided to stop making white on white dots. I do not have enough for the back! I have a bit of the border I am going to piece in and pray to the quilting gods that it is enough to make a back!
