One More Month

I'm a little concerned, I've got about 60 pieces right now, and I'm not sure I can make up the rest to get to 100. Ideally I'd like to make about 120 because I know things will not come out good, or they'll break etc, maybe 100 is possible, but 120 is out of the picture. There's one more reduction firing between now and the show, and maybe three more oxidation firings, but I've never really done oxidation, I'm not a fan of it, and I'm totally unfamiliar with what it'll do with the glazes, but I'm not optimistic.
To be honest I really have no idea of what to make. Like of that 100 how much of each thing should I be making? For example how many mugs is good? how many cups? how many etc... I really have no idea. This is totally uncharted territory for me, it's things I've never though about before. I really need some help, like right now I have 10 coffee mugs, should I make 10 more? Will they sell? if not I'll be stuck with a bunch of mugs, maybe that's a good thing because I could easily make them into x-mass gifts. Not as easy to do with tea pots, its hard to give away something that takes so much time and effort to make.
