Not sure about on-line stamp places, but I'd check e-bay. Good luck with your search

One thing, there is a company called Stamp' UP similar to scrapbook parties. Go on line if you do not have a consultant in your area. They have a large variety of stamps and they are not cheap, but good quality. Also Close to My Heart which is scrap booking but has an excellent selection of clear plastic stamps. Both can be bought on line. Do you have a large Walmart or Hobby Lobby?

Stamping or stenciling would be a great alternative to wallpaper -- cheaper, easier, and no peeling! I've been thinking about doing some stenciling in my house (when I get some other projects done). I hadn't really considered using stamps, although now that I think about it, my mother used stamps in a bathroom in a summer cottage we had when I was a kid. I think she made her own stamps, but I'm not sure out of what. It came out well, though, and gave it just the right rustic/primitive/cottage-y look. One advantage of stencils over stamps would be that you could do multi-colored designs. Also, I think there's a greater variety of ready-made stencils available, including some historical designs (colonial, Arts & Crafts, Shaker, etc.). Try looking on eBay for stamps and stencils. Just be sure that the scale of the design is right - it can be hard to tell from photos. Is this the article on wall stamping that you mentioned?

StampinUp has vellum printed with small white snowflakes. They also carry snowflake stamps. I used these items to make candles. They carry the sheer ribbon at a great price too. You can stamp a large snowflake on the vellum using the Versamark pad. Then sprinkle the white embossing powder over. Heat the flake with a heat gun. It is very beautiful. If you want to add glitter, restamp with the Versamark, and sprinkle the glitter over the sticky Versamark area. It is very beautiful when done. Hope this helps. Stampimup is online. They also have representatives. It was so easy, that I made a lot of them for gifts.
