I don't really like the weight and hand of most of the Marcus repros that I've bought compared to Moda or Windham. Some of the Marcus fabrics I've bought shrink terribly and it's perceptibly thinner than Windham - and both of those are thinner than Moda.
But, Marcus has authentic-looking repros, so I keep buying and pre-shrinking and starching.
