Heather, you are hiding your question when you put it under another topic. I might suggest that you will get more response if you post it as a new topic.
Also, did you search the web first? You might try going to www.yahoo.com and searching for "homemade wallpaper paste" or going to ask.com (no www) and searching just the way you have asked the question above. I'm sure that there will be plenty of links that will lead you in the right direction.
