About "wrapped bubbles":
Instead of canvas, I stretch bubble wrap onto a stretcher frame.
Or I first laminate bubble wrap onto canvas and then stretch it onto a stretcher frame.
Whereby my paint application takes place on the thin wooden strips around (=artist's frame).
About bubble wrap: The quality of bubble wrap varies widely - thicker foils usually have a surface that can be stretched smoothly, thinner foils can often not be stretched out so smoothly, therefore giving the picture a more restless, sometimes wrinkled surface and is therefore a desired partial aspect.
