Vorto vs. slab.

I'm back to basics today. Making some old fav. pieces to fill a back order. How varied my range has become. From this minimal style porcelain pourer, to slab rolled with texture and washed back glaze. When does one pull back a range. And when do you tell a fav. retailer you no longer make a certain style, even though it's still selling. My sanity verses paying the bills.
