I hear you gramma nancy, recently I just deleted hundreds of things both here and in my email that ordinarily I would have kept -- and I know there are things I'm going to regret deleting, I just haven't found some of those yet.
There are a number of mottled wide backings out right now. There is always the problem of how long ago did you get it and if it is currently available now or not. So was it within the last year? With Covid issues in addition to the usual design cycle there isn't a lot of back stock left any more.
Any other hints you can give, like the width? That there is no selvedge information is actually a clue in itself (and don't get me started on backings that are print from edge to edge except for great big huge company branding that go an inch or more into the pattern...)
Are there any shops that you definitely prefer or wouldn't go to?
And finally, if someone has it in their stash -- how much are you needing? Looks like maybe you need one more strip for binding or a border?
