Here is the banner I made for @-clairity. TO MAKE IT A BANNER: Use this image and put it in a project. Go to the "featured project section" and select it as your featured project, and change the title to "why I scratch," or whatever you want it to be. DO NOT CLICK OK. In a NEW TAB, open scratch and unshare the project. Go to the previous tab and click OK. CLOSE OUT BOTH TABS and then re-open scratch, and you will have a banner.
