"You keep using that word.I do not think it means what you think it means."(William Goldman, The Princess Bride)
the last few years I've been seeing more and more quilters, or, more
specifically, quilt bloggers, using the term "low volume" in reference
to a quilt. I believe what they are actually talking about is low contrast. I imagine we all have those things that irk the heck out of us. This is one of those things for me.VOLUME:noun
You could have a low volume of quilts, meaning that you only have a few of them, as VOLUME speaks to an amount or quantity of something. But if you are talking about the lack of differences in the prints in a quilt, that quilt would lack CONTRAST, "therelativedifferencebetweenlightanddarkareasofaprint". Volume already has a plethora of definitions, I don't think it needs other.
