1) a scale of about 1:6 (like what a Barbie doll would use) because I expect that scale, though an artificial constraint, would help create a unifying theme to the collection as a whole (and because that would allow me to include Vitra chairs which are fabulous).
2) chairs made by artists (like Sally Davies) and craftsmen. Thus, I mostly focus on those made by individuals (I find much of these chairs on Etsy.com, which makes sense as that site focuses on hand-made objects).
3) chairs that bear a certain presence, whether from its spirit or the mark of their maker. It's hard to explain this element but it's why most factory-mades wouldn't fit my collection as the nature of how they were made logically results in a certain sterility. The presence of the hand--and transcendence of the hand--must make itself discernible. I suppose an example is the Cordillera chair (though it's not featured here as a mini).
I hope the chairs I present will fit the defined parameters for creating this particular colleciton.
