I dont have any idea what it is, unfortunately, but i absolutely love it....

It's pretty.

Wow, lovely!

I can't help identify it but it did remind me just a little bit of this Ferm Living paper.

It looks like Designer Guild they do foil background with print. You may not find it on their website but I would send this image to them.

Graham Brown carries a wide selection of wallpaper not sure they have this one.

It is Hibiscus gift wrap by Snow & Graham. I bought a sheet to frame. It's hard to find. You can check Snow & Graham's site for online retailers. I know that Broadway paper has some.

I have this paper, and it was sold as sheets of paper (like wrapping paper) when i bought it - I don't know if it was every sold as wall paper.

I mounted the sheets on square canvas for artwork over my bed and loved it (temporary as it was)

I bought it at Blick art store in San Diego. It was a few dollars a sheet and I purchased it about a year ago.

They have this at Black Ink in Harvard Square for $3/sheet. Not sure if they have it at the Boston store.

I just found it on the snow and graham website:

Many thanks to everyone for their suggestions. I ordered four sheets from Broadway Paper. It is as lovely as promised and now I need to think up a project -- since pasting single sheets of wrapping paper all over my entryway is a bigger challenge that I think I am up for.
