Standard Post-Its are 3' x 3', so convert your measurements to inches and divide by three to get the possible number of Post-Its across and down. Of course, using more colors or smaller tiles will probably take much longer. Theoretically, you could use this software to create mosaics of any square, colorful objects, so there really isn't a need to limit yourself to the Post-It color palettes. 6) An idea of what picture you would like to put on the wall. 5) Some wall space, and the means to measure it. NOTE - The software will be able to tell you exactly how many of each color you need. You could just eyeball it off of your computer screen, but that would drive me batty. 2) mtPaint software 3) A color printer - semi-optional - used to print the final design. You will need: 1) A computer running either Windows or Linux. Note that I only have created the palettes using Sunbrite and Aquatic so far, so they are all in that color scheme. I'm also working on a really short summary page, as it only takes about 3 minutes tops to make one of the images, and the instructions look like it would take hours. UPDATE: I'm digging around on the Wikimedia Commons site and will convert a few more images, as it will take quite a while to get the actual mosaics completed. Also thanks to the mtPaint developers, as without that software, this would be infinitely more difficult. Many thanks to the original for the inspiration, and to all of the other Post-It mosaic designers out there. You can even use this technique to convert an image into any mosaic tile medium. Post-Its are not outrageously expensive, and this technique can be used with any square colored bits of paper, so if you have the time to cut up construction paper or colored copy paper and tape and/or glue them to a wall, you could certainly do so.

While I would love to have Photoshop at work, it's simply not going to happen, so I did a little searching and found a terrific open source app that does the job well. That looked to be a perfect project that the kids could work on over time, and would certainly brighten up some unused wall space. One thing that caught my eye was the Post-It mosaic of Elvis that made the online rounds a little while back. I work at a non-profit facility with kids and have been looking for projects to work on with them that won't cost a fortune.
