I never realized I could just check that box to allow me to post in a dead thread...so I am reviving this thread to talk about this disc:
The background was done like most of my nebula backgrounds - A bed of detergent in a circular pan, and a detergent/dye/fabric softener mix placed on top using eyedroppers and then swirled around with a toothpick. Softener is just added to lower the density of the dye a bit to prevent it from sinking into the bed.
The attached thumbnails show the bed and dye mixes (1), the bed prior to mixing (2), and the bed after mixing (3) that I used for this disc:
The background of the Floyd disc was essentially the same thing. But rather than completely random lines (pic 2), I made straight lines of alternating colors (gun metal, blue, aqua, turquoise). For the red tye dye above, I made circular swirls from the outside in, and then radial lines back and forth, like spokes. But the Floyd disc I just made a bunch of smaller circles.
I really think the key to these is the circular shaped/disc sized container that I generally use. This keeps everything looking pretty much exactly how it looks before you lay the disc down, rather than using a plate and letting everything spread much more.
The order of steps for the Floyd disc was:
1) dip dye the black of Pink Floyd, and the black on the face (but not the black of the shadow)
2) weed off the background and do the tye dye
3) weed the letters and paint those pink (pink, bright red, and fl yellow)
4) remask and uncover the face
Then all the colors on the face were simply painted on (just straight detergent/dye mix), trying to follow a negative color version of the face I found on google by searching "pink Floyd the wall face"
That was done in multiple steps (probably 5 or 6), since I tried to avoid doing any parts that were touching each other at the same time, and there are some areas that are layers of colors.
