I was making a polka dot quilt with a white on white dot background. Sure enough I ran out of the background. I searched everywhere for over a year and was never able to find it. You would think that white on white dots would be pretty standard. I challenge you to find any! I've learned many of the above mentioned lessons the hard way. The quilt did eventually get finished and I'm keeping it for myself because I worked so hard finding the fabric and "making do".
