banquet for the fodder

I am inspired by ghosts art - it has spawned an idea of mine.

1. Find some thin cardboard, maybe cereal boxes would do.
2. Cut a large variety of templates out of the cardboard, like the arrows that are common in ghosts art, but other templates too.
3. Stick the sticky half of a velcro on the four corners of each template
4. Have a few master cardboard sheets that have openings of various sizes to accommodate the templates and have the soft velcro side covering one side.
5. Start with whatever the canvas material is, I don't know what would be best.
6. Buy one or two dozen spray paint cans of various colours.
7. Using the template and the master board, place the individual templates wherever you want them, use one or more colours to spray the template, remove it
8. Wait for it to dry, (how long does it take?)
9. Change the template, or reuse it on a different spot, then repeat from step 7.
10. Potentially precede the use of template with some free hand spraying to provide a background.
11. Make sure to do it in a well ventilated area, and in my case as I am highly allergic to any form of toxicity, have a good mask and protective eye wear.

If ever I find the right combination of time/money, maybe I will investigate doing this.

Update: Another idea I had after posting this would be to get a bunch of sharpies of various colours and widths - there may be times where you would want to outline the spray painted template in a similar or different colour.
