I'm with Nonnie on this one. Since it is a denim quilt, it will not require a batting. I would tie small knots in the Stars, either in the points, or in the center of the stars, or maybe even a combo. If you trim them close, they will not take away from the print. I am not sure that you can stitch denim with clear thread, either nylon or polyester.....I too am a Dallas fan, and would love to have that print. Do you know who made it? I am sure that he will love his treasure, and it will be warm to boot! If the Dallas print is 100% cotton, you may see if they offer it in fleece, and that would make it easier to tie and increase the warmth for an "at home--mid-winter game!"
Go Cowboys! We are rooting for our boys to take it all the way to the super bowl this year, which just so happens to be being played at our brand new stadium...I am sure he will love his new quilt! (Hurry, preseason is just around the corner!) LOL Have fun!
