I saw your fabric when you posted it and thought it was probably from the 60's or 70's. Not 'vintage' enough for me as I like fabric from the 1920 or 1930 era. I think you just need to put your fabrics up for sale and label them cotton or silk or whatever. Everyone is different about what they like to buy and you may just find that one person who wants it now.

from dictionary.com:
vin·tage   /ˈvɪntɪdʒ/ Show Spelled [vin-tij] Show IPA noun, adjective, verb, -taged, -tag·ing.

adjective
7. of or pertaining to wines or winemaking.
8. being of a specified vintage: Vintage wines are usually more expensive than nonvintage wines.
9. representing the high quality of a past time: vintage cars; vintage movies.
10. old-fashioned or obsolete: vintage jokes.
11. being the best of its kind: They praised the play as vintage O'Neill.

As someone else said, vintage basically applies to wine making. But usage changes over time. So #6, #9 and #10 in the definition seem to apply to older fabric. I think you could also say 'vintage' applies to anything no longer in production or manufactured or created a long time ago.
Basically, most words mean what most people "think" they mean in their own world of knowledge. So some equate vintage with 'antique'(however that applies to fabric I don't know). I wouldn't take it personally. You certainly were only trying to give an accurate description as you saw it.
Nice fabrics by the way.

Well, it seems I have really stirred up a hornets' nest. I accepted the apology. We need to get on with being a great board and let by gones be by gones. IF you want to look at the fabric posted, it is at:

Green Heron was gracious enough to post a pic on that site to see if that was what I was looking for. I'll give it another day or two and then close the post. I just wanted some Civil War Repro without spending money. Will post other things to sell later, but probably not "vintage" fabric.

Interesting that we fell into a discussion like this. It is possible that there is no defined idea of what qualifies as "vintage fabric". I wonder if any of us knows a quilt appraiser who might help us?

I don't know a quilt appraiser and if I did, I couldn't afford to pay them to look at the fabric.......

Me too!
