I'm using the "closed form" idea for these pumpkins. If I don't quite have enough clay left for a good stem I roll out a small coil which I insert in the neck of the pot and keep on throwing. Sometimes, if there's enough clay to work with I pull the stem like I would pull a handle for a mug.
A couple glazes I like for these are a satin burnt orange and a speckled off-white. Colors you might consider natural, although I'm not trying for realistic.
Acorn finials- I throw these upside down, trim the rounded top, then attach a small ball of clay and throw the little pointy part. Glaze? Can't decide yet.
French butter crocks. A customer requested the bird design. Naturally, that means making several since the lids on these sometimes develop a hair-line crack. Frustrating.
