Adding my two cents' worth, it's important to remember that if you don't already have a buyer who picked out the colors, the quilt will only appeal to people who like the combinations you chose (count me in that group).
Someone else already mentioned, but it bears repeating: You can always lower the price.
And if you decrease it you will attract people who feel they're getting a bargain. Go to Etsy.com and Quilts4Sale.com to get an idea of what to charge, and have your minimum in mind. Put out good photos, because this is obviously well-made. And don't forget to include the cost of shipping or get an estimate that you can state as an additional cost.
Most of all, try to have some fun with it, the way you had fun putting this together - nicely done btw.
