The trick to using a not-quite-right fabric is to add more fabrics. This obviously works better in a scrap quilt than a planned quilt.
My experience with fabric.com isn't the best. First, they say they have something (on their site) and then later, after I have ordered and paid, they say they don't. I've had that happen probably 10 times and seldom shop there anymore. If I planned on it for a particular quilt,I am out of luck. Second, the fabrics I've received don't look like they do on my monitor - and I check it on several monitors before I order. I've got two bolts downstairs right now that meet that description and no idea of when I'll ever use them for for what I'll use them. They sure don't work with the project for which I bought them!
I hope you have better luck with them.
