Made for us out of bleached 7 oz. 100% cotton duck and sewn with cotton thread. (Hard to find, so we're making them). The duck is not pre-shrunk so there will be some shrinkage. They are perfect for dyeing, painting, stamping or marbling and you can make some fun stuff to sell, give or keep. I love the idea of banners! I've actually never made one and don't know what I would do with it if I did, but I get excited every time I see them. These come with a wooden dowel and end-balls which can be slipped out while you're working on them. Hemmed all around. Neat-o!
