There are many ways of conveying information on a blog; text and images being the two most widely used. Many infographics combine both these elements to provide a visual way of presenting text information.
Make your own infogaphic (no fancy imaging software needed, you can draw it on paper and photograph it if you want) to convey any element of your craft(s). It can be just for fun or a thoroughly researched presentation of an idea/finding.
I blogged about the creation of these infographics way back last May, when I created the fiber tracking stash table of doom (or yarn tracking as it is so innocently named in my system).
But basically these are representations of the current state of my stash and is my way of feeling in control of my yarn stash. These are tools to help me tell myself a story, also for some reason I really like creating tables and working with data.
