50 Medium JAR sketches
200 Medium BOWL sketches
1 water flask per sketch (summoned and foraged items don't work...grrr)
1 Medium block of clay per sketch
Don't worry about the firing sheets at this time. (Will explain shortly.)
Start on the pottery wheel with the med JARS, continue till it becomes a trivial
thing for you (You can't make med BOWLS till then). Next move to the med BOWLS
and continue till you become a Master Potter. At this point you can move to
the more profitable and nifty items.
Sheets are pricey, and you just never fail at the kiln. It's best to destroy your successes since you'll loose money if you fire up and sell the med JARS and BOWLS (at least that's what I hear).
