Stumbled on this, an absolutely fascinating exposition on crafting bean bags for juggling/footbagging. Well structured & written, hundreds of pages of pdf's.

On the meta, there's a bittersweet feeling - discovering these "early internet" (i.e. pre-enshittification/sloppification) gems is an increasingly rare experience.

Happily surprised to see Joshua Clifton's designs appearing on Hacker News, thanks for posting it :)

I know many jugglers in the circus community who really enjoyed the process of making their own beanbags from his designs, I just never expected to see it mentioned here, haha.

Very nice!

I wonder if the author can do a Parker Football?
