many people fold their fabric raw edge to raw edge because it was bought for clothing and it needed to be wider than half...big people often need this extra width.... you don't know it was bought for quilting in the first place... it may well have been a way for them to tell which was pre-washed and which wasn't... common techique in earlier years... and the wrong side out fabric? well those are older companies... ALL fabric used to be folded this way a long time ago... it protects it from being sun-faded...that's why they used to be folded with a little trianglular 'bed-turn-down' thingy on the top...so we could see the right side...
