A water-soluble substrate (10), and more particularly a water-soluble substrate that is resistant to contact with small amounts of water, and methods of making the same are disclosed. At least one of the substrate's surfaces (12, 14) comprises first discrete zones (20) having a water- solubility which is less than the water-solubility of said water-soluble substrate. The first discrete zones (20) represent from 10% to 90% of the surface area of said first or second surface.
