There must be no less sponge on the cover of the paint box. The sponge on the lid of the paint box is to prevent the paint from drying in the box. Hard-cover paint boxes usually have sponges in their lids. After each extrusion of paint or spray painting, wet the sponge and cover the box, which can also moisturize for a period of time, but the sponge will still dry if it is not moisturized for a long time.

The role of pigment sponge

Using a sponge to wipe the pigment on the drawing paper can create a mottled effect, especially when thicker pigments are used, this effect will be stronger. The steps of sponge painting include using different dilutions of pigments and different kinds of sponges to draw a work or part of a work with different color levels.

Try several different types of sponges, such as natural or artificial, delicate or rough. Sponge can absorb a lot of pigments, draw pictures with high water content, or touch the pictures with little pressure to create fine effects.
