A process for making a sheet article, comprising the steps of:

• a) preparing a wet pre-mixture comprising a water-soluble polymer and a surfactant and having a viscosity of from 1,000 cps to 25,000 cps measured at 40° C. and 1 s−1;
• b) aerating said wet pre-mixture to form an aerated wet pre-mixture having a density of from 0.05 to 0.5 g/ml;
• c) aging said aerated wet pre-mixture for at least 5 min;
• d) forming said aged aerated wet pre-mixture into a sheet having opposing first and second sides;
• and
• e) drying said formed sheet for a drying time of from 1 minute to 60 minutes to make the sheet article.
