I use a lot of accets from Clip Paint Studio's platform when I need something quick and easy. Some of these include the main notebook image. The sticky notes, and the sideways note paper.

Below are the various buttons/titles I've made for this site, sorted alphabetically. Feel free to use them, edit or remix them, bodge together the letters, and whatever else you could think of with it! Credit is not necessary, although I ask that you make your derivative works open to other people using them, too :)
