Color Bar postcards - due March 28th

Have you ever noticed the strange little squares and circles of color on the edges of packages?

They are known as registration marks or color bars and are used by printers to check alignment and color density.  They are so ubiquitous I no longer even notice them, but once you start looking you'll find them everywhere.

Doris had a fabulous idea for a swap - turn these little bits of color into a work of art.  Here's an example she created to give you an idea of what she's talking about:

Start saving those blocks now - you've got until March 28th to turn them into a postcard!

  • Create up to four postcards
  • Your art must contain the actual color bars cut from packaging (no fair printing examples from the internet)
  • It's okay to incorporate other media or images
  • Your design can be figurative or abstract, it's up to you

Mail your cards by March 28th to:

  1. So I'm not the only one who saves these???? :P

  2. Some time the ends of fabric have similar dots, can I use that as well??
