A Google image search would be your best bet. If you have any of the selvage with the name of the vendor and print that would help. eQuilter.com has the most extensive collection of quilt cottons online.
The reverse image search got me closer than my keyword searches had (it hadn’t crossed my mind to try it, for some reason), but I might be out of luck. The seller wasn’t the creator, so didn’t have any extra info on where the fabric came from. I’ll check equilter when I have a bit more time.
There is a new shop called Faithful Remnant on Hydraulic not far from MakeICT. They Have a huge selection but so have limited hours. Great place to check out
