I am a packrat by nature(I think it's genetic because my mother does it too...), so I have been hoarding blue jeans to cut up for years. I tell my friends and neighbors when they're done with their jeans, I can use 'em! The backing was actually a fleece blanket that was given to me. It had something embroidered in the corner that you couldn't tell what it was anymore, so I just cut that part off :) The floral material was once a pretty winter dress. The fabric is similar in texture to the denim and nearly as thick. So all in all the only thing I bought to make this quilt was the denim thread. Mine measures 28 1/4" x 28 1/4". I didn't follow the directions she gives for binding on the site, I mitered the corners of my binding.
