9/5: hinges

I'm working on two pamphlets that use hinges to add pages to an accordion fold.  Hinges are so useful but also vexatious.  Among other things, they can bulk up a project, and that's one of the things that was getting me down.  Then I tried using onionskin to make the hinges, and that de-bulked them!  I'm really happy with the results so far, and I hope the exclamation mark on that last sentence isn't premature.
