I agree...solid shape and pipe in details. otherwise I think you might have alot of breakage. You could do a solid color for the background and then do the details on top so you dont see alot of the cookie. good luck
I sell on ebay ALL the time. I also sell for others. If I am seeling for another person, I take 30% off the final auction price + they pay for the insert fee. If you go to an ebay store and have them sell for you that is what they take out. Good luck!
