The first one of these and one that is good for beginning painters is the “Blow-Out”, using straws to move the thinned paint in the direction that you want it to go.
For this you will lay a base of either White or Black onto your canvas. Into the base you will drop colors into it in the shape of flower petals. Then take a straw and gently blow the paint from the center out and sometimes back again.
Colors I used for “Orange Blow-Out” are: Black, Dk Burgundy, bright Orange, cad Red Light, Cad Yellow Medium and quite a lot of metallic gold. Blow & tilt your canvas until you get a design that is appealing. Lay it flat (level) and allow to dry.
In trying to recreate this exact design, I found less paint is better. If the design doesn’t turn out as you had hoped, you can always use it as a background for other artwork (on top).
