This blows my mind! I’m not a big crocheter, but am seriously considering doing this! If anyone’s tried this I’d love to hear about it.
Have you guys heard of Crochet by Numbers? I found the group on Ravelry, and some amazing pics there! Their website is www.crochetbynumbers.com.
Here’s one of the inventor’s own projects. See website above for lots more! There are photo and video tutorials on the website, as well as a sample patterns to try before you dive in. I’m just finishing up a project before I do mine.
