Regarding your undercut, I think you could have brought your clay about half-way up on that little bump before you poured your plaster the first time and you would have been okay and ended up with a four-piece - or maybe three piece? - mold. I might have placed the graining effect slightly higher on the bump to keep from creating a lock also, but not to worry. Don't forget that you can make keys after the plaster cures by digging into it with a melon scoop or some other tool, but your solution of putting keys in your wet plaster should work fine. You'll probably want to tool them a bit before your next pour.

I think you're on the right track. After all, a mold is just a thing to hold your slip in place. You'll have some seam lines to clean up, but that's par for the course.

Wendy will probably give you much better advice on this one. I've only done a few of these and she's done bunches, so this is all second nature to her.

Keep it up!
