My choice from my various attempts for the class ATC swap. You can see the first "prototypes" below. I also found the soap webbing is better on glossy cardstock. The soap webbing is easy to do. In a small container mix 2T water, 1/4C fabric paint, 1T clear dish liquid. Using a drinking straw placed straight down into the container blow slowly and pass strips of cardstock over the bubbles as they rise to the top of the container. It's easier to use strips. I sprayed over the dried finished product with a mister for a second color. I added a bit of glitter glue for the eyes and colored around the edges with a contrasting pigment ink.
Maybe this is better?
Let's see then, how about the discus -- colors are too boring....
This was my first idea - nope, the koi is too big for the ATC.
The soap webbing looks good.
