Calla Lily Vases: Developing the Form

I like where I've arrived. Of course, I did earlier too. Every improvement feels great. I suppose there are many more to go, in everything that can develop. Here's the story of one development.:

I've liked the form of calla lilies, a graceful, loose, wavy curve. Thought several years ago I'd try to make vases in a similar shape.

OK. Rather clumsy, and a flared shape isn't good for many kinds of flower arrangements  -- they flop.

Sometime later, in a class I learned this idea. Thank you again, Reiko Campbell.

Interesting. How to make it better?

I like the looseness of both of these early ones, the curves, the cut top. Not the stems I didn't attach well enough. They broke, immediately. And the shape of the pot? Eh. And the proportions? Something very wrong.

Next try:

 Ah, better with a flared base for stability. Stability is a big issue for vases. Bouquets are so often top heavy, and cantilevered arrangements are tempting. The vase needs to stand up under all sorts of inspiration.

 But stiff and a bit dull.Try this:

Much better with a looser shape. I like the emphasis on the flowers. Thought I'd try to make them realistic.

 

 Not enough control. Forget it. Better like I did it before, just something in the glaze that marks the flowers as a bit different from the body of the vase. Note: development is not, nothing like, a straight line of progress.
 
 So what shapes really work to make something that holds flower stems close together, is stable, and looks graceful and organic? These seem more successful.

I started adding a leaf, as the vases got bigger.

 But get rid of those horizontal throwing rings. They fight with the general vertical form. Here are the current best, and a new glazing idea that I like. Wonder what's next...
