some opus practice. these are made of dripped water color paint on paper. the paper is surfaced with gel medium, so i could stitch on it
the top two photos are playing with the mathematical term ' error function.' seems to me that it applies to things other than math, too.
in the bottom photo, i had picked up some scraps of embroidery thread from the table and hand-stitched them on under some netting. when i was almost finished, i saw the shape of a women in the threads...so i added a heart.
