String Gel Texture and Hidden Imprints

This recently completed 12"x12" stretched canvas has a "secret underground..."

... as these close-ups show: 

Clicking on the above close-up to enlarge it, you can see, on the left, a faint imprint made with my 6"x6" stencil Palm Fronds Silhouette Small. On the right, you can see a faint imprint made with my 9"x12" stencil Prayer Flags. 

Ditto for the above, except that here you see a faint imprint made with Prayer Flags.

Ditto -- Prayer Flags.

The original painting, created with these 2 stencils and a few layers of paint, had not turned out to suit me -- so I painted over it with a water-thinned layer of white gesso.  Then I started the new painting that appears at the top of this post by drizzling string gel over the surface and letting it dry.  Then I began adding new layers of paint, using sea sponges.  This kind of flexible applicator gave me the freedom to blend colors and to apply thin layers were desired.
