Here is a blog for you to submit letters as written by Harry Potter characters. It'd kind of like headcanons and fanfictions, but in letter form. No restrictions. Have fun with it. :) Just submit the text and I'll make the graphic.
An anon requested a Lupin/Tonks one. I haven’t been too creative lately but I hope this is okay. If you guys can think of any cuter Lupin/Tonks ideas, send them in! (there was a typo so i fixed it, which is why i reposted.)
