I've never done this before, and I need to start preparing now for the convention on April 10th. Thing is, I'm not completely sure what the best plan would be. I've had this weekly strip since November '08, so that's 68 strips so far. One idea is to take everything I have up to this point, plus some extra stuff, and make that into a little book. But I've wondered if that's throwing too large a percentage of what I've got out there in one go, since the whole point is to get people to follow you around, so to speak. Maybe it would be smarter to take a very small number of those 68 strips and make it a mini booklet? I just don't know.

If anyone has any suggestions based on experience, plus any other tips based on the material I have (for anyone who's seen it!), I'd be very grateful for the advice.

Thanks!

Have you considered making a bunch of small books and packaging them together with an envelope or something as a collection?
That way people could choose whether they wanted the entire collection or go with one of the smaller minis. I really wouldn't worry about putting too much out, if an online strip is ongoing you'd just be allowing people a chance to catch up with what you've got.
I'd also recommend getting a tablecloth to make your table more eye-catching, signs of course, also other people might want to trade with you so decide if you're up for that as well. Hopefully that's helpful.
