I made my son a quilt using 2 thrift store sheets for the batting, as I was replicating his worn out quilt my mother and grandmother had made together that he had been using since he was in his teens. The original quilt had heavy muslin feed sacks and a sheet for batting and was fairly heavy. He loved that feeling of weight so I used the sheets to match what he had before. It came out almost the same as the original in weight and feel.
