I don't know about high quality (there are all different vendors), but I have had great luck with American Blinds and Wallpaper.

Here is a link that might be useful: ABWF

I'm doing wallpaper as well. Do you have any specific style or theme in mind? That might help us to direct you to the right resources. I think www.americanblinds.com is a good place to start. You can search by color, style, or subject.

There are a number of high end brands that really have beautiful wallpaper which you won't find on most wallpaper websites. These are usually sold to the trade only but you can buy them through some of the discount decorating websites. Attigmag has a nice list of sources to start with including some of the higher end lines.

Thanks for the quick replies and resources.

LOL- I really know nothing about the quality of wallpaper! I was just trying to steer away from the ugly, shiny orange and brown flowers we had in my house growing up.

I don't have a specific theme in mind but am visualizing a tone on tone look- I keep seeing pictures of beautiful bathrooms with box molding and deep, rich looking textured papers on top.

IMO, wallpaper never goes out of style, it's the most classic way to decorate! Here's a website which I ordered a sample of my future wallpaper from, they sent me a large sheet and I love it. BTW, I have wallpaper in the bathroom too, and I just love it. I don't know how to do a hyper-link:

Here's the wallpaper I'm putting on one large wall only, in the dining room. It will have white/cream beadboard below it while the rest of the walls in there will be painted THE lightest yellow I can find. I'm more excited about this wallpaper than I am with the other remodel! lol

Me too! (both love wallpaper as well as hoping to put it in our main floor guest bath, but only if I can find exactly what I want ...)

Anyway, I like Design Your Wall.

Here's another good website to try. Design By Color has a nice variety of wallcoverings sorted by color and has a tool that let's you preview the wallpaper in a variety of settings. I found this helpful for getting a sense of scale with prints. You can also order a sample of any paper for only $0.99 vs. $5.00 for the same thing on other sites.

Brewster Wallcoverings has a similarly wide array of papers and a visualizing tool but they don't offer samples.
