First off I must say it is absolutely beautiful!! Makes me want to do some more experimenting with designing... You did a piece of art! I personally would say it the 500-600 range... eventhough it may very well be worth more too... Fabic and time add up and I usually don't keep great track of how much I spend on fabric as I pulling from stock and restocking. Then time is hard to figure.. Quilting cost is the easiest to come up with price.. It does make me want to do one similar!:)
