Holly's birthday is coming up and I wanted to make her something nice. Aparna suggested recording a video for her, but I can't think of what to say. We'll see. Anyway, I decided to write her a letter as well, since it is eternally my (unrealised) goal to send more letters. I used large index cards, though, and I don't have any suitably-sized envelopes. I have loads of tutorials for making envelopes, so I'll have to locate some nice paper.
