This is an easy project.
I purchased a plastic "sun catcher" at the local craft store.
This is a product designed for painting.
However I took it and scanned it.
Then imported the image - full size - into my graphics program.
I colored the various sections on the screen.
Finally I printed the design on CLEAR SuperCal Decal Paper.
After spraying and letting dry, I put the SuperCal decal into water and
slid the decal onto the back of the plastic sun catcher -
printed side against the plastic.
See for yourself ... it worked great. Click on image to enlarge.
