Awesome input, girls!  Thanks so much for posting.  

Ah, that's a lovely list, Vili!  I don't think I'd need crates because I wouldn't have that many books to display (just multiple copies of a couple of books), but I plan to take picture stands to tip one copy of the book up for display.  I totally didn't think of extra pens... good call.  

  (I would have a pen, but I wouldn't have thought of a spare.)
Yes, I'm definitely getting bookmarks printed before I do this.  

  It is good to have freebies that people can take away and remember you by.
Ah, yes, the in-person marketing.  That's going to be the hardest part for me, but practice makes perfect.  

Ciela, that's quite an amazing idea.  I would definitely start a thread for that, either here or in HW projects, at some point.  While I love the idea of a HW table, my practical side wishes to urge caution.  The thing about a conference is that you need to have stock on-hand, which means you need capital to buy it.  I don't know that I, personally, have the funds to buy significant quantities of a lot of books; I'm already going to be in quite a bit getting stock of my own books.  Also, what about profits?  If I sell your books, do I get to keep any of the profits as my commission?  How do I get the earnings back to you?  And so on.
However, I would absolutely be willing to put out bookmarks, business cards, or other free literature for friends on my table (at my discretion, of course) from other HW authors.  Then no funds need exchanged; you just need to send me the material and I will give it away.  (We were talking about that in another thread.  When I get bookmarks printed, I shall be swapping them.)  I'd even be willing to go so far as to put together a "packet" of literature, if I had enough, maybe bearing the Holy Worlds label.
