Any advice on framing a 1876 centennial flag? It's cotton (I'm pretty sure) and in very fragile condition. I was thinking of a DCO mount on a fabric covered backing. The chop size is 47 x 34 and I was also wondering what thickness Optium to recommend (I was thinking 4.5mm or even 6mm but the prices are crazy). I'm concerned the acrylic will bow if it's too thin.
