After the paint is squirted onto the shaving cream gently use a comb to create the marbling effect. For best results soak the fabric in water and wring damp. The moisture helps the paint adhere.
Just lay the damp fabric on top of the paint and then remove fabric carefully to not disturb the design. Lay fabric in the sun to dry BUT beware the paint is soaked all the way thru the fabric and will leave paint on whatever surface it is placed on.
I placed it outside on the grass in the sun.
