if you're interested in where the urban sketching icon came from, have a look at this image. this image is from a trip I took to christchurch New Zealand.
I was really taken with the library. It turns out the library is a really fantastic building that has not just books but also shares knowledge and skills. I learned how to create buttons and so I used this image to create a button which I wear on my jacket and I thought it was a great image that we could use as the icon for the Sketching group.
