I was going to suggest that you buy another shower curtain to use for the fabric, but it looks like they don't make Graphite any more. They sell fabric, but they don't have Graphite in that either.

Would you be at all interested in matching the gray color in a patterned fabric for your Roman shade?

I don't know the manufacturer, but if the color is discontinued do an ebay search for "Restoration Hardware graphite". This will bring up bedding and curtains in that color. Then use the fabric as you will.

I'd checked that for her, sonicmom.

They have 2 bath towels, a pillow sham and a silk quilt. I also checked online for any manufacturer who sold 'graphite' linen, but there is no guarantee that it would match he color she has in her shower curtain.

I've linked a solid 'gray' linen on eBay, but it may not match. There are some great contemporary fabrics there with dark gray in them that might work well.

Thanks so much for all the help!!!!!
