Wow! You have done a lot of work getting stuff ready. I have one of those basting guns that I don't use for basting, but it might be a quick way to tack price tags to your fabric. I will bring it if you want me to, along with extra tacks, and we can do that before the sale. Straight pins would work, but might stick someone, and these wouldn't. Call me if you want to use it and I will put it in my basket...
