I've compiled a page of miscellaneous journal mishaps here (i.e. ink splatters, blood stains, tear drops, coffee stains, etc.) that are always fun to use in journal-based RPs.
The page is filled with thumbnails of all the images, so one only needs to click on the thumbnail to go to the larger image to snatch up the URL. I uploaded everything to tinypic so you don't need to worry about hotlinking! (tinypic has no issues with hotlinking that I know of. Someone correct me on this if I'm wrong)
The page is always growing, so if there's any other sort of mishaps you use/find, it would be kindly appreciated if you sent them my way or linked them below!
