Very nice. Looks like you did a really good job. I'd be curious to know what you used for the back.
And yes, I'm absolutely certain you could find someone who'd be willing to buy such a quilt. I would be willing, if I had any money to spare. (And if there weren't a slight chance of hurting my mom's feelings by buying someone else's quilt... VERY slight, as she's up to her eyeballs in unfinished projects... but she's still my mommy.)
