LOVE your latest 'quilt'. Man, that is TINY!@!
As for your concern about naming the work:
A rose by any other name would smell as sweet.
I love these kinds of discussions on an intellectual basis but I have a thought on this matter.
All English speaking people can look at grass and call it 'green' (speaking of its color). Calling it green doesn't make it green. And it isn't called green because of the wavelength of light that it reflects. It is called green because English speakers long ago 'agreed' with one another to call that wavelength green. And by and large later generations of English speakers have agreed. With fine tunings like: Forest green, pine green, spring green, yellow green, blue green, teal, etc. ;-) Things are called by names and defined in ways to SIMPLIFY communication. Then you get some intellectual like me pontificating about something to people outside its realm and what is said gets taken as gospel and spread around as fact.
Whatever we call these artifacts of fabric and thread and technology, they are physical manifestations of LOVE. Either love of the creative process, love of the craft, love of the product, love of praise, or my favorite, LOVE FOR THE RECIPIENT. (who is sometimes ourselves ;-) )
So call your lovely pieces and your WHIYM whatever you feel best conveys your meaning, depending on to whom you are speaking. If they aren't versed in quilt speech, it's a blanket/coverlet (which is an honorable thing to be). If they are some sort of pompous expert, call it fabric art, or whatever. Won't make the item itself intrinsically any different or alter its true worth one iota.
