Hi Guys, I just received (via UPS) a new sail for my kid's Opti. Unfortunately, the tube in which it was sent got bent (perhaps almost folded in half?) in transit. The tube actually split open in one place but the sail fabric did not get torn or cut. However, the sail has some pretty obvious creases, including up through the middle of the window panel, and extending about 1/2 of the way up the sail above the window (approximately in the area of max camber). Are there any ways to remove (or at least reduce the severity of) these creases - especially those in the plastic window material? I'm tempted to run a cool/warm iron (perhaps over another piece of fabric) over the creases, but I want to run this problem past the experts first. I expect that in every loft sail material must occasionally accidentally get sharp creases in it, and that resourceful sailmakers would probably have found a nifty way of getting them out. Any advice you can give will be much appreciated! Thanks, Neil
