We include two examples of a 2-ply business card in our Recycled Sample Pack. A 32pt Brown Kraft card sample is an example of using two of the same stocks to double the thickness. A 34pt W1S card sample is a great example of combining two different stocks as it uses 100% Recycled Brown Kraft on one side and 17pt Smooth Uncoated White on the other.
If you would like to receive samples of other unique 2-ply combinations such as W1S Wood or Premium Black, you can order them in a Specialty Sample Pack.
