Clothworks and adding thickness

I am interested in drawing boat sails. I want to use the air function of clotheworks to fill the sails with wind to give them a natural look. Is it possible to add thickness to a clotheworks made sail? I want to 3D print the boats and sails.

You can use fredo6’s joint push pull, available there :

as for the sails, you can also get good results with soap skin & bubble plugin, as clothwork sometimes generate very complex geometry (I haven’t used it recently though)
