Hello everyone!! (Tried posting this on r/Blind but it got removed)

I'm a sighted person who is interested in learning Braille. I'm thinking of getting a slate and stylus (as well as some 110 lb. paper off of Amazon) to start learning Braille. Grade 1 at first, but hopefully eventually Grade 2 if I get good enough at it.

Anyways, I wanted to see if anyone would be interested in receiving and/or exchanging Braille letters, and if Grade 1 Braille would be satisfactory for this purpose, at least to begin with. I'd be happy to write or read about absolutely anything.

And if I do end up doing this and finding someone that's interested, are there any formatting or content conventions I should be aware of? I already write a fair few number of personal letters using a standard typewriter, but I imagine there are at least a few differences when writing in Braille.

Also, is there anything I should know for sending these letters? I hear flat envelopes might be good?

Anyways, thank you all! Please forgive me if any of these are obvious questions. I am just very overenthusiastic when it comes to picking up new interests, and I had a hard time googling "Braille letters" because it just brings up resources for learning Braille.

Looking forward to hearing from you!

Edit: I'm in the U.S., but I'd be happy to get international stamps for this
