Preserving Newsprint

How can you preserve newspaper articles and the like in your scrapbook without them yellowing? A friend turned me on to a product called Archival Mista while back. Archival Misttakes the acid out of the paper, and your newsprint won't yellow over time! It's really cool stuff.

It's available at most craft and scrapbook stores, and I've even seen it at Target. You can also order it online here: Archival Mist
