Red rose print cotton feed sack, opened flat, about 44" x 36" overall. This one is nice and bright without fading or a lot of spotting, but it does have a large tear 'flap' with ragged edges, about 4" x 4". (Sorry, I forgot to take a photo of that.)
It would make a fine cutter if you can work around that, or would be easy to patch or mend... I always think patches on old sacks are a plus, rather than a minus! Added points if you use hand sewing or a contrasting color fabric on the hole.
