Search Google for green yellow floral upholstery fabric and a bunch of choices pop up.

This P Kaufmann Clarice has similar colors - See it here.

And at this link below, you'll see images of other fabric with your colors in them. Maybe one will appeal to you.

do you have a better image of the fabric for reference or a name for the Thibaut fabric?

I don't have a direct answer or know your budget. That said I highly recommend JoAnn Fabrics if you have one in your area. They have a big area of Waverly decorator (wide width) fabrics and you can get 20% of coupons pretty easily.

It is a good resource for fabric on a tight budget.

I found it on a UK Thibaut site. It's from the Richmond Collection, and this pattern is 'Longwood'. 69 British pounds per meter.

• Ref: F94130
• Colour: Yellow and Beige

"Curated with a deep regard for classic American design and reverence for
British style, this Limited Edition Collection is filled with powerful
statement patterns."

I found it on eBay in a different colorway for $40 per yard,

I wasn't able to add the eBay photo in the above reply for some reason, but here it is.

Thank you Annie! You did the legwork. I was a little worried I would get chastised a bit for mentioning a "low brow" place. I have just always wanted to live in a beautiful place whatever my budget was. Even now when I have a bigger budget, I love to find a bargain!

Not sure why posters keep showing blue fabrics............?

Here's the Thibaut Fabric

Here are some white/yellow/green fabrics from Fabric Guru. I also checked Robert Allen and they don't have anything like this.

Try Calico Corners too.
