$400 stretch goal? (Patreon)

Hey everyone! I just noticed that we're only $9 short of $400. And wow! This is really exciting, I never expected to find so much support from the community for my writing projects.  This is really exciting!  I hate to sound like a broken record, but I do hope that all of you realize how much this means to me.  I started this Patreon as a lark, hoping that it might help me out with a few monthly bills but I didn't really expect much.  But your support has really helped me to devote more time to writing.

Anyway, since we're so close to $400, I feel like I ought to offer some sort of bonus stretch goal for when we hit that number.  I just don't know what I can offer, since there's not much I can do besides write.

So I'll ask you guys, any ideas of what I should do to celebrate $400, if and when it happens? :)
